The specs for AMD’s upcoming Polaris 10 GPU have allegedly leaked, with a brand new card appearing in the SiSoft Sandra benchmark database. AMD’s Polaris GPUs will be coming in two flavours - Polaris 11 and Polaris 10. Don’t let the numbers fool you either; Polaris 11 will be focused at both the desktop and mobile markets, while the lower Polaris 10 GPUs will in fact be for the high-end desktop gaming market.

Onto the specs then, and the Polaris 10 represents a massive die shrink as we knew already, with AMD manufacturing this on the 14nm FinFET fabrication process. Compare this to the 28nm used for the Fury X and there’s going to be a jump in both performance per watt and efficiency.

It’s not clear at the moment which graphics card this chip is going to be aimed at, but it certainly looks cut down and suggests there could be more to come. It reportedly packs 40 Compute Units (CUs) in comparison to the 64 of the Fury X, housing 2560 Stream Processors. The report also suggest a clock speed of 800Mhz with total performance in the region of 4.0 TFLOPs.

On the memory side of things the Polaris 10 comes equipped with 8GB GDDR5 memory. No sign of HBM at all, indicating possibly a mid-tier model. That’s on a 256-bit memory interface providing a total memory bandwidth of 192 GB/s.

From the looks of things it’s lower than expected specs suggest this is the cut-down chip which is going to feature in the eventual Radeon R9 480X.

There's still plenty of question marks surrounding what's been shown here, and it certainly doesn't paint the full picture of what we can expect from Polaris. From the looks of things you can expect a full reveal from AMD in June at Computex.
