Intel, AMD...
Hello
in Italy there is a big diffusion of Amd. Intel is considered an expensive and useless brand compared to Amd. In our newsgroups there is a big quantity of trouble messages with Amd, and not with Intel. I would know, as a little survey, who win between Amd and Intel, what is your opinion about.... Thanks! -- Mirko (18,?,CE) "Quello che capita" driver Powered by Intel P4 2.80C and Asus Motherboard "comunque di solito chi ha AMD ha una certa cultura informatica per cui è più facile che posti nei NG."

Bleeding edge game players will take exception to some of my statements, and I realize that they are a special case. I am making general statements about the average user. In my opinion, which is not all that important, there is no real difference between the competing processors from AMD and Intel, except the price. For most users there is no noticable performance difference no matter what software you are running. Years ago it used to be that AMD lagged behind Intel for floating point performance, but even then you would not notice the difference unless you were doing modelling of the atmosphere or something like that. If you are a bleeding-edge game player, the difference between the two makes no real difference since the graphics card does most of the work. For the money you save getting an AMD you can get that much better a GPU and more system memory. In addition, you may squeeze out a few more frames per second. Benchmarks (see www.tomshardware.com) currently show the latest from AMD being faster than the latest from Intel for this. But you must ask yourself if the difference in frame rates is really that great, since frame rates in the lower two hundred range are way faster than your brain will notice. And even if the latest game taxes the CPU, other bottlenecks like memory bandwidth have a far greater effect(IMHO). For business applications, benchmarks showing the difference between the processors are measured in seconds or tenths of seconds. Faster memory makes the biggest difference because more data is moved per unit time, but even then you are talking about sub-second measurements. The bottom line is the price difference. Even if the current benchmarks showed that Intel edged AMD, I would still get the AMD because for the lower price I could get more of something else, like memory or better GPU. The performance difference has long since ceased to be anything worth considering except in exceptional cases. I would add that a true 64 bit machine like AMD offers provides added incentive to get it, to take advantage of software written for 64 bits. Sorry if what I have written was a bit long, and if it incites flames. That is not my intention. Eli |

In my opinion, which is not all that important, there is no real difference between the competing processors from AMD and Intel, except the price. Not quite. Look at benchmarks for Doom 3 for example. Even a $1,000 Pentium 4 3.4 ghz EE doesn't come close to the performance of a $285 Athlon 64 3500+ running Doom 3. http://www.anandtech.com/cpuchipsets...spx?i=2149&p=7 A $185 Athlon 64 3200+ socket 754 beats the $1,000 Pentium 4 3.4 ghz EE running Business Winstone 2004. It isn't just a price difference, but the higher level Athlon 64 chips provide performance for some very widely used applications that no Intel desktop processor can match. The Athlon 64 also allows upgrades to 64 bit software. The Intel 64 bit desktop processors are expensive and very hard to find(unless you want to buy a system with one from Dell). For most users there is no noticable performance difference no matter what software you are running. Years ago it used to be that AMD lagged behind Intel for floating point performance, but even then you would not notice the difference unless you were doing modelling of the atmosphere or something like that. If you are a bleeding-edge game player, the difference between the two makes no real difference since the graphics card does most of the work. Not true for Doom 3 and many other games. http://www.anandtech.com/cpuchipsets...spx?i=2149&p=7 A chain is only as strong as its weakest link. At least with an Athlon 64 3500+ or higher processor, a high end video card can finally achieve its potential in many games. For the money you save getting an AMD you can get that much better a GPU and more system memory. In addition, you may squeeze out a few more frames per second.

I do state further down that you get more bang for your buck with the AMD. I guess my point is that if you were to be given two machines running Doom3, one with the AMD and the other with the Intel, you would be very hard pressed to determine which one was which, based on gameplay. The performance difference between their top-line chips is not so great in terms of ability to notice, in my opinion. The happy thing is that not only do you get a few more fps with AMD, but it costs way less. It's just that the price diff is the major difference, not the (noticable) performance. Stated another way, suppose the AMD cost $1000 and the Intel cost $185. Would you shell out that much more money for those extra 5.4 frames or would 77.3 be perfectly fine? It is misleading to say that there is a 7% performance difference in those benchmarks at 1280x1024. It is accurate to say there is a 7% frame rate difference, but performance is arguably something noticed by the user. As frame rates increase, the meaning of a 7% increase lessens. The difference between 32 fps and 26.6 fps is also 7%, but you will notice lag and jerky movements on screen at 26.6fps. That same 7% difference in these benchmarks will not be noticed. One thing to note: if you look at the performance curves on the first page of that article, you can clearly see that moving from a Radeon 9800 Pro to a GeForce 6800 with the same CPU makes a HUGE difference. At 1280x1024 you go from about 30 fps to about 75 fps. This clearly shows that the GPU does the heavy lifting. By the way, as far as full motion is concerned, the human eye percieves it fully at a rate of 30 to 32 fps. The idea is to keep the game engine portion from stuttering so that the GPU can maintain full motion. I would be interested to have benchmarks that record numbers and lengths of stalls in gameplay over unit time rather than a frame rate per second. A $185 Athlon 64 3200+ socket 754 beats the $1,000 Pentium 4 3.4 ghz EE running Business Winstone 2004. Yeah, I concede this point for heavy business apps like database transaction servers and heavy e-commerce apps. But I do say that I was stating opinions about the average user. Eli |

Nothing from Intel at a similar price comes close. But that is not what the comparison is. The comparison is based on "performance" between both competitor's top-line chips. In no way am I saying that Intel's latest is as fast as the latest form AMD. What I am saying is that I doubt seriously if, given the same GPU and memory config, you will notice a difference in everyday apps. Eli |

Eli I doubt that many buyers care what the performance is of the top offerings from either company. It's quite rare for someone to pay in excess of $800 for a single desktop/PC CPU, even if they'd spend $400 for a video card. |

I'm considering AMD instead of Intel. But, a friend of mine who works as a Techie in a Television Station, is very familiar with Microcomputers, and he has been on Seminars where they were discussing the merits and flaws of both Intel and AMD. He was told that AMD typically does NOT do the CHECKSUMS as often, and to the same degree, as Intel. Is this true, and could this result in data corruption? Checksums? Checksums are normally done in software, so are completely CPU-independent. If your data is sensitive, implement checksums in your applications. In my opinion, which is not all that important, there is no real difference between the competing processors from AMD and Intel, except the price. Then what about the adage: You get what you pay for? Does Intel COSTmore because it's WORTH more? A non-argument. Cost is regulated by market forces which have little or nothing to do with quality or performance. Take cars. A Toyota is cheaper than a Ford, yet more reliable and fuel-efficient. But hey, maybe the Ford is 'worth' more... Or to stay on-topic for computing, take Rambus memory- it's been consistently vastly more expensive than plain old SDRAM derivatives, yet apart from a brief period in the early P4 era it only just managed to equal (DDR-)SDRAM performance, it ran hotter and was less flexible (max 2 modules per channel with a performance loss for 2 as compared to 1). That's not to say that cheaper is always better, it's just to illustrate the pointlessness of such an argument. For most users there is no noticable performance difference no matter what software you are running. Years ago it used to be that AMD lagged behind Intel for floating point performance, but even then you would not notice the difference unless you were doing modelling of the atmosphere or something like that. ....or AUTOCAD, or 3D modelling, or photo and text editing? I'm just wondering. Text editing can be done perfectly satisfactorily on a Digital PDP-11 from the 1970s... Photoshop is FPU intensive when running filters and utilises SSE(2) extensions. Before AMD supported SSE2, Intel and AMD CPUs were about equal, since SSE2 support AMD wins hands down, particularly when measured on a performance/dollar scale. See: http://reviews.zdnet.co.uk/0,39023100,39164010-4,00.htm In Autocad an Athlon 64 3400+ performs on average 8.3% better than a similarly priced P4-3200 See: http://www.xbitlabs.com/articles/cpu...4-3400_16.html If you are a bleeding-edge game player, the difference between the two makes no real difference since the graphics card does most of the work. For the money you save getting an AMD you can get that much better a GPU and more system memory. In addition, you may squeeze out a few more frames per second. Benchmarks (see www.tomshardware.com) currently show the latest from AMD being faster than the latest from Intel for this. But you must ask yourself if the difference in frame rates is really that great, since frame rates in the lower two hundred range are way faster than your brain will notice. And even if the latest game taxes the CPU, other bottlenecks like memory bandwidth have a far greater effect(IMHO). Are we talking faster frame rates AND high resolution, at the same time? Whatever you want. Either a lot more of one or a little more of both. It's just a ratio you can set as user. More power just gives you a little more choice. For business applications, benchmarks showing the difference between the processors are measured in seconds or tenths of seconds. In the computer world, SECONDS is an awfully long time! Such a time lag is a VERY SIGNIFICANT difference. So assuming there is a 1-second advantage for CPU x in Excel (Winstone Business 2004 benchmark, say). Assume doing 12 such calculations per day, five days a week, makes one minute's difference. That means a whole lunch break per year (allowing for holidays etc), assuming the employee in question never ever does anything parallel... That must compare to nose-picking in terms of time wastage (plus the obvious fact that an employee incapable of multitasking is a far bigger problem in itself) Faster memory makes the biggest difference because more data is moved per unit time, but even then you are talking about sub-second measurements. But isn't faster memory related to CPU speed? No. The most important factors are the speed of the memory chips (far slower than CPUs these days) and the width of the bus with which to access them, determining how many chips can be accessed in parallel. A close second is the latency, how long it takes for a request for data from the CPU to get to the memory and back. Using two memory controllers in parallel can double maximum throughput, a step Apple incidentally took in the mid 1990s, years before PC chipset makers thought of it (and even then it was the rather obscure ALi who first implemented it on the little-known Aladdin 7 chipset, which could take both Intel and AMD Socket 7 chips). These days most performance chipsets have dual channel access. Latency can be addressed by CPU cacheing (mainstream CPUs now have a Megabyte of L2 cache) and integrating memory controllers into the CPU (which AMD has done in the Athlon 64 series). Pure CPU speed can even be a handicap, because it means the CPU is running so much faster than the memory that it spends an awful length of time idle waiting for data. The first Celeron CPUs based on the P4 illustrated that, with the CPU running up to 28 times faster than the bus that connects it to the outside world and 14 times faster than the best memory it could be paired up with, yet a tiny 128KB cache which couldn't compensate for it. The bottom line is the price difference. Even if the current benchmarks showed that Intel edged AMD, I would still get the AMD because for the lower price I could get more of something else, like memory or better GPU. The performance difference has long since ceased to be anything worth considering except in exceptional cases. I guess you could say that a $200 difference may be NAME related. But what does it REALLY mean when Intel costs about $800 MORE than the equivalen AMD? It means that the marketplace is prepared to pay $800 more for snake oil brand x rather than snake oil brand y. Assuming (as I do, incidentally) that the intrinsic value of Intel and AMD chips is almost identical, if Intel can get away with charging more, who are we to complain. AMD would do the same if they could- and that they can't is merely a product of market perceptions. In fact, as savvy consumers our response should be to favour the better value over the inflated repuation, a choice that collectively will push up AMD prices and drop Intel prices. And if Intel ever becomes cheaper whilst delivering comparable intrinsic value- hell, buy Intel. I would add that a true 64 bit machine like AMD offers provides added incentive to get it, to take advantage of software written for 64 bits. But, isn't the Intel P4 a 64 bit processor? No. The only thing '64-bit' about the P4 is it's bus, but then Intel (and AMD) buses have been 64b wide since the days of the first Pentium in 1993. What is commonly meant by '64b' is that is can address 64b of (virtual) data and process 64b long instructions. In that sense the P4 is firmly 32 bit, at least, except for the very latest EMT64-P4 CPUs, which (just like the Athlon 64, incidentally) consist of a traditional 32b chip with a set of 64b extensions bolted on. 'True' 64b chips are rare beasts, Intel has its Itanium, Sun the UltraSparc, and HP the PA-RISC64 and Alpha CPUs. MIPS also had a few in times gone by, and IBM has its Power-series (with derivatives in Apple G5 systems). However these chips are rarely seen on the desktop (OK, I'm typing this on an Ultrasparc IIi-based machine, but this is not a typical desktop ), mainly because they don't run Windows (except the Alpha which ran NT) and are prohibitively expensive. 64b is a double-edged sword too, because having to double the length of all addresses seriously bloats code, which decreases performance. 64b is mainly hype, the prime use for most mortals is that it allows more than 4GB of RAM on a fairly simple motherboard. And just for the record, I own more Intel-based systems (4 in use) than AMD-based ones (2). I greatly admire Intel CPUs from a technical point of view, as do I AMD CPUs and other more obscure stuff as well- I particularly like Intel's tendency to over-engineer slightly. But when price becomes a factor (as it always is in the real world), you want the most bang for your buck. And Intel usually (though not always!) does not deliver. As an excercise, take a good benchmark in an application you consider important. Then look up the prices of the CPUs in a pricewatch or whatever. Divide the performance by the price. Then list the CPUs in terms of price/performance. Finally choose the minimum performance (and/or the maximum price) you are prepared to accept and discard the CPUs that fail that mark. Choose the cheapest of what is left. That is the rational way to choose a CPU. 7 times out of 10 that will lead to an AMD CPU at the moment. The remainder will usually be laptops, where the Intel Pentium-M and Celeron-M lines are quite remarkable, particularly as they combine excellent performance with extreme economy in electrical terms. And as for reliability- there are two relevant points: 1) the economic lifespan of a system 2) the technical lifespan of a system In business most computers are written of over 3 years, which means that almost always the techinical lifespan is much longer. For home use 5 years is more common and then technical issues become more important. A system is good if its technical lifespan is longer than its economic one. The technical bottleneck is almost always the moving parts. CPUs don't move. If you intend to play with your hardware, rebuild your computers regularly and swap components, the physical strenght of CPUs becomes relevant, and until the advent of the Athlon 64 Intel had a considerable advantage due to their aforementioned over-engineering. But idiots like me account for less than one percent of users. If you're one of the 99%, your CPU will stay in one place and never be at risk from the dreaded core crunch (which incidentally CAN happen with older Intel P3 CPUs too, a fact I can unfortunately relate out of personal experience- although the cause was a badly secured heatsink which bounced around too much during a long drive. That (as with similar AMD incidents) was user negligence, not a design fault. |
