drkohler said: I think these latest devoper units come with 8G of gddr5 ram. Usually developer units ship with double the ram than in the end product. This is consistent with the 4G ram rumour in other places. The "2.2G video ram" is obviously the space software reserved as available for the gpu within those 8gigs in the developer units. Also note that that it's not 8 cores, it's 4 Bulldozer modules. Each module shares an fpu (the reason why Bulldozer performs "poorly" against similar Intel counterparts whose cores have dedicated fpus). |
Well I just think this "2.2GB reserved VRAM" kind of destroy the good about the unified RAM... if you have 4GB os shared RAM then the OS have to dinamicly share between system and graphics like 360 do... now if you want to reserve RAM for graphics then the better thing is make your system with 2GB GDDR5 for graphics and 2GB DDR3 (or 4) for system.
This amount of reserved VRAM is weird.
And yeap the each Bulldozer core have two fpu units... so just one part of the CPU is duplicated... when you have a real dual-core you need to duplicate almost everything except the shared cache. 4-core Bulldozer with a good clock is fine for games even more if the "secret sauce" do some CPU related things (like the Eurogamer rumor said).
Tomorrow there is a new VGLeaks article but I thing nothing too diffent from what the other rumors said will be shared with us.
