While Mobipicker can not confirm the authenticity of the leak, it seems like we finally have a sneak peek into the AMD Polaris 10 specs.

For the uninitiated, Polaris – AMD’s next-generation GPU architecture – will come in two distinct flavors: Polaris 10 and Polaris 11. While Polaris 11 will be targeted at both mobile as well desktop markets, its sibling Polaris 10 will be more focused on the high-end desktop gaming market.

As for the leaked AMD Polaris specs, first seen in a benchmark database, it is virtually confirmed that Polaris will introduce a massive die shrink as AMD is manufacturing it using the 14nm FinFET fabrication process. Considering the huge gap with the 28nm in the older Fury X, it is evident that Polaris is going to be a big leap forward in terms of both efficiency and performance-per-watt.

Polaris 10 will reportedly come bundled with 40 Compute Units (CUs) as compared to the 64 in the Fury X. In addition, it will boast 2560 Stream Processors alongside clock speed of 800 MHz with overall performance within the range of 4.0 TFLOPs.

The leaked benchmarks also suggest that AMD Polaris specs will include 8GB DDR5 memory, but there is no sign of HBM. The 256-bit memory interface will provide a cumulative memory bandwidth of 192Gbps.

Nothing is known about any possible AMD Polaris 10 release date yet. Neither is known anything about the graphic card which it will be targeted at.

    256 bit interface better be wrong.

    • R Valencia

      256 bit GDDR5X ~= 512 bit GDDR5

        yea since it has twice the speed

    So this is like an worse 390? i know the bus is half the width and prolly will use half the watts as well, 380x does close to 4 tflops…. performance should be better.

      We won’t know for sure until it’s released. I’m a bit confused about it as well, but having a max power consumption in stock configurations around 85W will make a nice difference. Performance may be the same or slightly better than a 390, but the TDP will be way lower. I think they’re just focusing on efficiency until HBM2 GPUs come out next year or late this year. NVIDIA’s always boasted a better perf/watt ratio, so perhaps AMD’s aiming for that this round? We won’t know until AMD releases the official details I suppose.

        I think that may be it. Personally, I’d love to see them bring out a 60w part like the 750Ti. Good 1080p performance that could be used with a decent 300w PSU would be a game changer for AMD.

        I like AMD and all, but the GPU I found myself recommending the most was the 750Ti, for people who wanted to pay as little as possible, and tinker around in their computer as little as possible.

          That was the idea of the Fury Nano, was a super small form factor with high performance with their HBM memory standard. If they use a 14nm process with the HBM2 version of the Nano, you could stuff that in a small form factor system with very low power requirements. But you’d benefit from severely high performance. And we know how great the perf/dollar ratio is with AMD, so building high perf budget PCs will definitely be a thing by mid next year. Not to mention Direct3D 12 and Vulkan are gaining traction as well.

          • tyler1489

            A 14nm, >100w, hbm2 new nano with 15 billion transistors back at the $650 would be perfect!

      Remember how the 5850 had 1600 Stream Processors, whereas two years later the 7850 had 1024, yet performed better? I think advancements in AMD’s Stream Processors mean that you can get better results, with a smaller number.

    lol the 800Mhz clock isn’t the official clock, this card is an engineering sample sent to third parties to test their board designs, and engineering samples are usually clocked much lower than their shipping clocks for stability until they hammer out the bugs.

    Final clocks should be above 1Ghz easily.
