※ 引述《ouyang (討厭TPA啦~~~~~~)》之銘言:
: XBOX720 還有 32MB的embedded RAM 可以做FreeAA
: SONY 就是學不會....
既然是談到 AA,那可以看看 FXAA 之父 Timothy Lottes 怎麼說:

引述的原文指出:
“On this platform I’d be concerned with memory bandwidth. Only DDR3 for
system/GPU memory pared with 32MB of “ESRAM” sounds troubling. 32MB of
ESRAM is only really enough to do forward shading with MSAA using only
32-bits/pixel color with 2xMSAA at 1080p or 4xMSAA at 720p. Anything else to
ESRAM would require tiling and resolves like on the Xbox360 (which would
likely be a DMA copy on 720) or attempting to use the slow DDR3 as a render
target.
I’d bet most titles attempting deferred shading will be stuck at 720p with
only poor post process AA (like FXAA). If this GPU is pre-GCN with a serious
performance gap to PS4, then this next Xbox will act like a boat anchor,
dragging down the min-spec target for cross-platform next-generation games.”
