The GT300/Fermi Thread - Part 2!

[saaya]

Well, I guess we can agree to disagree then. Granted, the Shaders, TMUs and ROPs are still called the same thing but look at the difference:

GF100:




GT200:

look at what? those are two different ways to illustrate a gpu, of course it looks very different

- Large dedicated (and unified) cache structure

evolution

- Fixed function stages are now integrated into each cluster (or SM as they were called on the GT200) through the Polymorph engine

tweak

- Texture units now have direct access to the cache structure

evolution

- Scalability through unified ROP + L2 + memory controller structure

tweak

- Dedicated L1 Load / Store cache

evolution

- Incorporates a raster engine into each GPC which groups the three pipeline stages (Edge Setup, Z-Cull and the Rasterizer)

tweak

- GDDR5 memory controller

thats a standard component, isnt it? its nothing special...

- DX11-necessary components such as a dedicated tessellator, etc.

weeeeelll we will see about that

i have to reword my statement though, there is def a lot more new stuff and improved stuff in gt300 vs gt200 than there is in rv870 vs rv770... rv870 seems to be 99% of a double pumped rv770, in gt300 there are at least a lot of tweaks and improvements over gt200, even though i wouldnt call it a new gpu. i think it doesnt deserve to be called GF100, it shouldbe GT300 imo... just like rv870 is just that, rv870, and not cypress, some new architecture or design etc... but hey, who cares

i think its funny that marketing has penetrated some chip companies so deeply that they even give their asics marketing friendly codenames
