Some specs for 1 of the 3 Vega SKU's leaked recently:



Only problem is, we don't know where that leaked SKU falls on the heirarchy. If it's the most powerful Vega chipset, it's kind of dissapointing, 12.5 AMD tflops is not likely to beat the 11 tflop 1080ti, let alone the 12 tflop Titan XP. If it's the middle or lowest Vega chipset though, it sounds pretty good, sounds like it can at least beat the standard 1080, which would be great depending on pricing. I'm hearing that the slowest of the 3 is going to be faster than the 1070, which suggests this might be the middle SKU.

Those specs have been known for over a year already. It's not really new.

However, according to the 3D Mark leak, Vega had a core clock of 1.2Ghz.

4096 Shaders * 2 instructions * 1.2Ghz Core clock. = 9.8 Teraflops. And that fits nicely in the roughly doubling of a Radeon RX 470/570.

We also need to keep in mind that Vega's NCU architecture adopts many of the advancements found in Maxwell and Pascal, so the amount of work it should be able to do should be vastly superior to that of Polaris and older Graphics Core Next designs.

With that, don't compare AMD's flops against nVidia's. It will never end well, it's inaccurate and doesn't tell the entire story, Especially when the chippy's aren't even on the market yet.

There is one thing worth remembering:

If Polaris can achieve 1,300MHz in the 580/70 and Vega's architecture is designed to achieve higher clock speeds, then that 1.2GHz from the engeenering sample used in the leaked benchmarks is not representative of the final performandce of the card.

Also, there's the idea (I don't remember where it comes from) that Vega will be a 12.5TFlops chip, which would put the end card at 1.5GHz.
