It's been another slow news day but now there's another piece of Radeon RX Vega news. A newly released Linux patch for AMD's GPU drivers reveals the Vega10 GPU has a similar core configuration as the Fiji-based Radeon R9 Fury series.
The source code reveals Vega10 has four shader engines, which is the same number as the Fiji GPU. Another variable hints there are 16 GCN compute units per shader, so assuming the number of stream processors per CU hasn't changed we're looking at a total of 4,096 stream processors, which implies a TMU count of 256.
The configuration may be the same but Vega promises a lot of changes under its hood. Vega10 will be manufactured on a 14nm process and is believed to feature a 2048-bit memory bus with HBM2.
At earlier reveals of the "Vega 10" package, you notice a large, somewhat square GPU die neighboring two smaller rectangular memory stack dies, which together sit on a shiny structure, which is the silicon interposer. The presence of just two memory stack dies sparked speculation that "Vega 10" features a narrower 2048-bit memory interface compared to the 4096-bit of "Fiji," but since the memory itself is newer-generation HBM2, which ticks at higher clocks, AMD could run them at double the memory clock as "Fiji" to arrive at the same bandwidth 512 GB/s.
An official showcase is expected by the end of this month.
