PS4 graphics to be PowerVR Series 6 ?

According to John Carmack, at least one of the next-gen consoles won't have an optical drive. Who's up for 25GB game downloads? :-) Well, Nintendo used to do fine with cartridges in the olden days. Perhaps they're going back to the modern equivalent of cartridges, flash memory thumb drives? Most modern SD flash cards are 8 to 16GB, meaning that they're already larger than or equal to DVD drives in capacity, and they are still growing. Blu-Ray disk don't seem like they offer enough of a cost advantage over flash drives. |

PS4 graphics to be PowerVR Series 6 ?
Comparing video RAM between the Dreamcast and PS2 is a bit like comparing
apples and oranges. The Dreamcast has 16 MB of 100 MHz system RAM on a 64-bit interface; and 8 MB of 100 MHz video RAM on a 64-bit interface. Memory bandwidth is thus 100 x 64 /8 = 800 MB/s, slight more than a Voodoo2. The architecture is pretty straightforward, similar to a PC's. The PS2 had 32 MB of Rambus-type system RAM with 3.2 GB/s of memory bandwidth. The 4 MB of video RAM was embedded into the GPU's chip package and had 9.6 GB/s memory bandwidth, so it functioned more like a large cache. The PS2's GPU could stream textures off system RAM faster than the Dreamcast could off local video RAM, provided the game developer exploited this capability. According to this document: http://www.technology.scee.net/files...PowerOfPS2.pdf The PS2 could also do both edge AA and even FSAA (with both supersampling and multisampling), but early games evidently didn't use them. Sony's early developments tools may have been crappy. -- "War is the continuation of politics by other means. It can therefore be said that politics is war without bloodshed while war is politics with bloodshed." "Jim" wrote in message ... "First of One" wrote Yep, ahead by about a year, until the PS2 came along. Dreamcast games looked better than early PS2 games. Dreamcast had double the VRAM so it didn't have use 640x480 and could do AA so it didn't have nasty jaggies. |

Perhaps it's just the laziness of developers, but as far as I've seen, the vast majority of PS2 games looked awful right up to the end. -Miles -- x y Z! |

Blu-Ray disk don't seem like they offer enough of a cost advantage over flash drives. A 50GB flash drive still costs many times (magnitudes) more than a 50GB Bluray disk, so it is highly unlikely that next consoles will use flash as medium. Besides that, game publishers clearly aim to move from physical distribution to electronic distribution, not only because it is cheaper, but also because it allows them to kill the 2nd hand market (games are locked to a console/user and can't be sold) and makes other licensing models (like time-based licensing where you buy playtime) possible.

Benjamin Oh please, I picked up 6 32Gb SDHC cards off of ebay for $8 a piece. So in a few years, its very possible youll see 50GB thumb drives or memory cards for retail at that price. You already can get 16 GB for under $10 at best buy all the time |

I picked up a 16GB Class 6 (highest speed class) SDHC card for $20 including shipping on Ebay. I'm sure it cost whoever was selling it much less for him to buy it. Besides that, game publishers clearly aim to move from physical distribution to electronic distribution, not only because it is cheaper, but also because it allows them to kill the 2nd hand market (games are locked to a console/user and can't be sold) and makes other licensing models (like time-based licensing where you buy playtime) possible. That's entirely possible, and that's the reason they'd want to get rid of the optical drive. A small flash drive slot would be a much more cost effective non-permanent storage medium than a disk drive. Physical distribution isn't going away, just the optical disk physical distribution. And you can't rely on the Internet to download your games when you need them. Yousuf Khan |

The PS2's GPU could stream textures off system RAM faster than the Dreamcast could off local video RAM, provided the game developer exploited this capability. You need the eDRAM's bandwidth to keep the pixel pipelines full. 3.2GB/s wont give you 2.4Gigatexels so its use for gfx is limited. RDRAM's high latency is another problem. So if you wanted to use any of the PS2's potential you had to use 8bit textures and sub SD res. Dreamcast used TBDR so it made better use of its bandwidth than a Voodoo2. Apples&Oranges According to this document: http://www.technology.scee.net/files...PowerOfPS2.pdf The PS2 could also do both edge AA and even FSAA (with both supersampling and multisampling), but early games evidently didn't use them. Sony's early developments tools may have been crappy. The AA page was vague. Multisampling didn't come until next year with the GeForce3 and with the GS's bandwidth it would be cheap to use. Jaggies are usually the #1 complaint about PS2 gfx. |

* GMAN:
Oh please, I picked up 6 32Gb SDHC cards off of ebay for $8 a piece. Yeah, great. I can have 50GB Bluray disks mass produced for less than $0.50 to $0.70 per disk, depending on how many I need. So in a few years, its very possible youll see 50GB thumb drives or memory cards for retail at that price. You already can get 16 GB for under $10 at best buy all the time Maybe. But it still means higher costs than optical media, no matter how you turn it, and doesn't change the fact that the game industry wants to get away from physical distribution. Benjamin |
