Vega's specs grow less vague

DRM finally did something good for us; revealing detailed information on AMD's new GPU.  In this case the DRM is a portion of the Linux kernel which interfaces with the GPU and some inquisitive minds dug through the code to find details on Vega, which will be supported by this new version of DRM.

This is still in the realms of rumour, but the source is very good as AMD would not likely enter the wrong specifications into this update.  According to the specs which wccftech compiled from the code, Vega features 64 compute units, each containing 64 GCN stream processors, the 4096 SPs will be split into four Shader Engines.  A little math, based on the stated performance figures of 12.5 TFLOLPS for FP32 and 25 TFLOPS for FP16 operations, the GPU should clock above 1.5GHz.  There were no details on the memory frequency though as it uses HBM2 we know it will have a 2048-bit interface which could lead to some interesting performance numbers.

"Thanks to the latest Linux graphics driver update submitted by AMD we now have detailed specifications of the upcoming Radeon RX Vega GPU. The DRM, Direct Rendering Manager, update to Linux was issued yesterday and it’s the first update to date that adds comprehensive Vega feature support to Linux. No doubt in preparation for Vega’s launch which is expected to take place at the end of the month."

Just as a clarification. DRM here stands for direct rendering manager, and has nothing whatsoever to do with Digital Rights Management.

Thanks for the clarification, was just about to go on a google expedition. I knew it wouldn't be DRM as in copy protection but had no idea what it meant otherwise.

Just to be clear that 12.5 TFLOPS and the requisite clock speed have nothing to do with this leak. Those are the announced values for the MI25 Radeon Instinct and likely slightly different (lower?) than consumer Vega.

The MI25 that is "passively" cooled, meaning cooled by server fans instead...
The MI25 that is said to be <300W (meaning 275-300, or they'd spec less to begin with)
The MI25 that lacks various parts that are not needed on compute card but is needed on graphics card...

All things considered, it's likely that the MI25 is clocked higher than consumer Vega will be.

Either that or we're back to AMD delivering furnaces in order to be able to compete at all...
