AMD Ryzen 3000 Zen 2 Matisse 12-Core Beast CPU Hits UserBenchmark Database
However, Su later hinted in a post-keynote interview that "you might expect that we will have more than eight cores." Well, here we are with a UserBenchmark database entry that was uncovered by notorious hardware sleuth Tum Apisak. The listing is for a 12-core, 24-thread SKU using the AM4 socket, which points directly to this being a mainstream Ryzen desktop processor.
The processor carries the string 2D3212BGMCWH2_37/34_N, with the "H2" portion of the string seemingly denoting that it is from the Matisse family of 7nm Zen 2 processors. We can also glean from the results that the processor has a base clock of 3.4GHz and an average boost clock of 3.6GHz. The boost clock seems a little on the low side (compared to its base clock), but we have to remember that this is an engineering sample and final clock speeds might not have been dialed in yet.
The folks at Tom's Hardware also noted that the Ryzen 3000 processor obtained a single-core floating point score of 130 points, which is roughly a 13 percent gain over the current generation Ryzen 7 2700X with similar clock speeds. If you recall, earlier reports suggested that we'd see a 13 percent improvement in instructions per clock (IPC) with Zen 2 compared to Zen+, so this result seems to back up those assertions.
Other items of note from the database entry are that the processor is equipped with 32MB of L3 cache and that it was tested using Hynix DDR4-2666 memory.
We should note that earlier rumors pointed towards 12-core/24-thread Ryzen 7 3700 and Ryzen 7 3700X processors priced at $299 and $329 respectively. At the time, it was alleged that the processors would have base/boost clocks of 3.8GHz/4.6GHz and 4.2GHz/5GHz respectively.
