Yeah, there's no way the FP32 TFLOPs is 4x. Xbox 1 X is 2560 shaders at 1172mhz for 6 TFLOPs. No way to get 24 TFLOPs in a console on 7nm. It could be FP16, or just their performance benchmarks taking the rest of the system into account. Can't understimate how much faster Zen 2 will be over Jaguar.

It probably is FP16. The leaks I've been seeing on Xbox 2 (Anaconda) show 12 TFlops, which is presumably FP32.

Cutdown card will have pretty much same performance at same clock vs full SKU
Same Rops, TMU, Memory bandwidth and only 10% less SP.I think 2-5% difference in games at same clock.

Anyone think AMD may be holding back a RX 5800? Which may only appear after Nvidia comes out with its refreshes?

It won't be as good. Lower clock, lower CU count. This is not he same design as in previous generations of AMD GPUs.

Yep.

Yep.
Read again what i said.AT same clock....only difference is 10% more SP.If you OC both at same clock, difference will be very small.Even smaller than 1060 3Gb vs 6GB at same clock because 1060 3Gb have less TMU.So we are talking about 2-5% max.

499$ GPU class.

Cut down version appears to be exactly what I predicted. 90-95% of RTX 2070.

scores are best API vs. best API, so some may be DX11 for one and DX12 or vulkan for the other

Slides are what were posted already. 1x8 + 1x6 is better than the expected 2x8 pin. Um, 7 phase board? Okay. Anyone remember how many power phases there were on RX Vega 64 reference cards?

Looks like performance for both the 5700 XT and 5700 vanilla are great. TDP on the other hand with a 1x8 + 1x6..... notice how there is absolutely no mention of power draw throughout the presentation. Probably looking at 225w TDP for the 5700 XT.

The rumors of the RTX super lineup is probably true if AMD's benchmarks hold up.

The 6 pin connector is there to facilitate the Overclocking potential in thse GPUs. At stock the GPU might actually be 225W power draw.
