1. TMUs are memory bound. You gain missed my Tomb Raider 2013 with 69 GB/s and R9-290 example.

2. Radeon HD 7950's 32 ROPS superior result says Hi. Any fill rates are bound by memory bandwidth. Adding another 16 ROPS ay 853Mhz on X1 would be nearly pointless.

If Radeon HD 7950 at 800Mhz is the top 32 ROPS ~= 240 GB/s example, the 16 ROP version would consume 120 GB/s. If normalize 120 GB/s at 800Mhz to 853Mhz it would yield 127.8 GB/s which is far higher than 7770/7790/R7-260X memory bandwidth limits.

Rebellion already explained why most X1's games are less than 1920x1080p i.e. ESRAM is too small for 1920x1080p and it needs "tiling tricks". Rebellion > you.

3. Stop posting crap posts. The prototype 7850 shows what it's 12 CU (768 stream processors and 48 TMUs) capabilities with higher memory bandwidth. Prototype 7850's 32 ROPS will be bound by memory bandwidth.

My POV is backed by Rebellion's POV.

Rebellion > you.

4. Consoles doesn't have PC's DirectX's sysmem1 (CPU) to sysmem2(Direct3D) to VRAM memory copy issues. Secondly, Xbox One's CPU (FCL type block) can directly communicate to the GPU (via host MMU).

5. An example on how R9-290 was reduce to near X1 Tomb Raider 2013 results by gimping memory bandwidth to 69 GB/s. Btw, my Mini-ITX box is limited by 16X PCI-E version 2 (8 GB/s-8 GB/s link) and dual channel DDR3-1333 memory i.e. it's Intel H67 chipset limitation. Your point 4 is a joke since 60 GB/s VRAM (i.e. 8 GB/s removed by 16X PCI-E version 2) didn't significantly change frame rate result.

For near X1 Tomb Raider 2013 result, my R9-290 has160 TMUs (from 40 CU x 4) and it was gimped by 69 GB/s memory bandwidth. Again, TMUs are memory bound. The same problem for my R9-290's 64 ROPS which is also gimped by 69 GB/s memory bandwidth.

6. You can't use Xbox 360's tiling example. Rebellion > you.

7. For Xbox One, it's an additional memory bandwidth for render targets.

8. ID's Megatexture doesn't work in Xbox 360's EDRAM, while AMD PRT/Tiled resource works with ESRAM. ID's Rage uses mega-texturing via GDDR3 and uses EDRAM just rendering targets.

9. Refer to point 8. You don't know the difference between Xbox 360 and Xbox One. Xbox One's GPU can happy do HDR 16 with FP filtering i.e. there's no need for Xbox 360's double frame buffer HDR workaround.

The existence of my 7950's 32 ROPS kills your PS4's 32 ROPS paper spec..

Fact: Rebellion > you.

Define "close".

1. "Tiling tricks" will enable TMUs to fetch textures from the fastest memory pool i.e. treat 32MB ESRAM as texture cache.

2. "Tiling tricks" will enable ROPS to read and write on the fastest memory pool i.e. treat 32MB ESRAM read/write cache.

3. I have defined my "close" as prototype 7850 with 1.32 TFLOPS with 153.6 GB/s memory bandwidth against R7-265 with 1.89 TFLOPS with 179 GB/s memory bandwidth.

4. Both 7770 and 7790/R7-260X doesn't have the option to scale towards 153.6 GB/s memory bandwidth.

5. I have shown R9-290 at 1Ghz being reduce to near X1 levels with Tomb Raider 2013 and 69 GB/s video memory bandwidth. AMD's Catalyst driver 14.1 restores clock speed based down-clocking i.e. I can target any video memory bandwidth from 38.4 GB/s to 320 GB/s and run Mantle i.e. the "console like APIs".

6. Xbox 360's connection between the GPU and EDRAM is limited to 32 GB/s which is different for Xbox One i.e. 204 GB/s.

7. Xbox 360's GPU's ROPS can't directly access main GDDR3 memory.

8. Xbox 360's GPU doesn't have hardware AMD PRT/Tiled Resource.

9. Xbox 360's GPU has pixel format issues that limits certain effects and causes excess memory usage e.g. double HDR frame buffer due to lower HDR FP 10bit precision format. You don't understand the difference between Xbox 360 and Xbox One.

You're going to be waiting quite a while for Second Son to go on sale on steam.

My statements are inline with AMD Gaming Evolved with Mantle developer Rebellion. The clueless is you.

To clarify, my "closing the gap" POV doesn't automatically means equal or exceed PS4. At best (with tiling tricks for memory related workaround), X1 runs like prototype 7850 with 12 CU/1.32 TFLOPS + 153.6 GB/s memory bandwidth and it's still inferior to retail 7850 and R7-265 (closest to PS4).

R7-265 (1.89 TFLOPS + 179 GB/s memory bandwidth) > retail 7850 (1.76 TFLOPS + 153.6 GB/s memory bandwidth) > prototype 7850 (1.32 TFLOPS + 153.6 GB/s memory bandwidth).

Rebellion is AMD Gaming Evolved Mantle developer. http://www.rebellion.co.uk/blog/2013/11/21/rebellion-throws-weight-behind-amd-mantle

Rebellion > you or any cows.

No, the new DX will close the gap with PS4. PS4 already has one of the best graphics API and it's similar to Mantle.

^Can you please give me a link where I can verify that? Or else you're just, you know, a liar.

mostly not into indie games so that's not a plus to me

Looks like DX12 will be a game changer for The One............can't wait for devs to take advantage.
