Civilization V
Our final game, Civilization V, gives us an interesting look at things that other RTSes cannot match, with a much weaker focus on shading in the game world and a much greater focus on creating the geometry needed to bring such a world to life. In doing so it uses a slew of DirectX 11 technologies, including tessellation for said geometry, driver command lists for reducing CPU overhead, and compute shaders for on-the-fly texture decompression.

Not at 176GB/s, unless they're clocking that GDDR5 VERY high. The 7790 is good for 96GB/s.Shut up and drink - Friday, March 22, 2013 - link
Sony's previous two consoles (PS2 and PS3)have traditionally favored high frequency/bandwidth proprietary Interconnects between components (see Cell's EIB) so this is likely where the "secret sauce" Sony R&D came in, thus facilitating the 176GB/S.AMD was quoted (can't find link) that said Sony engineering would be excluded if/when they release a PC variant of said APU.

Very, very interesting indeed. It tallies well with the numbers. There was me thinking they had bolted Pitcairn onto the side of their CPUs but this combo might make more sense (and yet also less sense).lopri - Friday, March 22, 2013 - link
Totally agree with memory size. At this performance and price level, 2 GB should be default.lopri - Friday, March 22, 2013 - link
Then again, it would be strange if AMD doesn't release "larger" cards based on this updated GCN core.silverblue - Friday, March 22, 2013 - link
Perhaps the reason for the lack of a 2GB version would be that it would be too close to the 7850...?CeriseCogburn - Sunday, March 24, 2013 - link
NO it SLOWS THE CARD DOWN with it's crappy amd core...Haven't you been paying attention for like the YEARS you've been here ?

I don't understand why you haven't been banned yet. You add nothing to the discussion with your posts other than vitriol. Please either be civil and logical, or go away.CeriseCogburn - Sunday, March 24, 2013 - link
AMD always releases 1GB models and 2GB models so the amd fanboys can quote the 1GB model cheapo powercolor low end price, claim it wins price perf, then go on raging about how the 2GB model covers the high end ...ROFL - That's what they do - they even do it when comparing to a 2GB nVidia, suddenly forgetting amd makes crapster 1GB they swore off years ago, even though that's the screamer amd fanboy price "they pay" because "it's such a deal! Man! "
Brainfart Bart they should be called.

Actually, they didn't with the 7770.Your constant whining is about as welcome as a bout of herpes, scram.
