Intel onboard GPU conflicting with CPU power

In some cases (Gigabyte), they even use 2oz copper for that, rather than the "normal" half ounce copper. Sometimes you see mention of that in some advertising blurb. Why on earth are they using such an antiquated measurement? It should be measured as 0.07mm. https://www.theinquirer.net/inquirer...oz-copper-lead You can see some layer stackup diagrams here. https://www.gigabyte.com/webpage/16/article_12_ud3.htm At one time, motherboards were four layer. When RAMBUS came out, those were six layer. I never used that stuff due to bad reviews. ROFL! "Rambus Incorporated, founded in 1990, is an American technology licensing company, and has also been labelled as a patent troll." The Gigabyte diagram indicates they used 8 layers on their X58 product. https://www.gigabyte.com/webpage/16/article_12_ud3.htm -- 63% of men have had sex in the shower.

It's more like a discussion with a chef in a kitchen, than with a machinist in a machine shop. Every profession has its own way of doing things. My policy is "we don't argue with success". If the methodology produces good results, who am I to argue with petty details :-) Paul |

The measurement that really annoys me is "mills". Some people think it means thousandths of an inch, some think it means millimetres. -- History teaches us that no other cause has brought more death than the word of god. -- Giulian Buzila |

Is it true that if you max out the GPU part of an Intel processor at the same time as all the normal cores, it can't do them all at once?* I run Boinc which can do calculations on both at once.* And if I use all the CPU cores, the GPU part goes about a 5th of the speed.* I guess the only other place this could happen is a game that multithreads on all the cores and also uses the graphics. Are you using a standalone GPU? If not, the CPU will be used to do on-board/in-chip graphics. -- @~@ Remain silent! Drink, Blink, Stretch!
