AMD Polaris 10 GPU Specs Leaked: 8GB GDDR5/X Memory, 36 CUs, 2304 GCN 4.0 Cores
AMD teased their 2016-2019 GPU roadmap at the Capsaicin event held during this year’s Game Developers Conference (GDC). The roadmap showcased their new Polaris architecture having 2.5x perf/watt improvement over the current gen 28nm based GPUs.
From what we know so far, the next-gen graphics processors include Polaris 10 and the lower-end Polaris 11 GPUs, of which specifications of the former have just leaked on the web.
As spotted on the SiSoft Sandra benchmarking database, Polaris 10 is equipped with an 8GB GDDR5/X memory and 256-bit wide memory bus. The GPU features 36 compute units (CUs) coupled with 2304 4th generation GCN cores.
In terms of clock speed, Polaris 10 GPU is clocked at 800Mhz with an effective memory of 6 GHz (1500 MHz), giving a bandwidth of around 192 GB/s. The clock speed is quite low for a 14nm FinFET based GPU, so chances are high that we are looking at an early engineering sample here.
Still, with its low clock speed and lower number of GCN cores, this particular Polaris 10 GPU did come ahead of the R9 290X which indicates better per clock performance than predecessors. Moreover, the GPU beat Nvidia GTX Titan Black in the benchmark, although the latter features a full GK110 chip.
