It is only a matter of time before AMD comes out with an accelerated processing unit (APU) based on its Zen microarchitecture. Giving us a glimpse at what AMD has in store is a new listing in SiSoftware's SANDRA benchmark database. One of the newest entries shows what looks to be an engineering sample of AMD's forthcoming Raven Ridge APUs, which may end up using the same Ryzen branding as AMD's desktop CPUs.
The engineering sample in question pairs Zen and Vega in one neat and tidy package. Most of the details in SANDRA's listing are now hidden, likely at the request of AMD, though screen captures taken from earlier in the day reveal quite a bit about the APU.
Codenamed "AMD Mandolin Raven," (though this has been since removed in the Sandra database) the APU features four physical CPU cores and eight threads with a 3GHz base clockspeed and 3.3GHz boost frequency. The chip also sports 2MB (4x512KB) of L2 cache and 4MB of L3 cache. On the GPU side of things, the APU has 11 compute units, presumably each with 64 stream processors. That gives it a total of 704 stream processors. The GPU is clocked at 800MHz.
Here is a look at some of the scores the chip obtained:
- Processor Arithmetic: 83.69 GOPS
- Processor Multi-Media: 149.30 Mpix/s
- GP (GPU/APU/CPU): 572.68 Mpix/s
There is a wide gap in those scores and AMD's Ryzen 7 1800X, as would be expected when comparing a budget APU with a top-end performance CPU. This might also be a mobile APU, or at least that is what the model sample ID suggests. It is is listed as "2M3001C3T4MF2_33/30_N." Using the decode ring above, that tells us this an ES1 engineering sample that is close to being a qualification sample. The "M" is what designates this as a mobile part.
Hat tip to Fudzilla for digging this one up. Based on earlier rumors, AMD may launch its Raven Ridge APUs in the second half of this year starting with its mobile lineup, followed by desktop variants in early 2018. If that is the case, there could be some interesting products from system builders this coming holiday season.
