AMD Ryzen Threadripper 3000 32-core CPU is more bad news for Intel

While there’s been little official word on AMD’s 3rd-generation Threadripper chips, the chip has made an appearance over on Geekbench. And while the results suggest that this chip may not deliver the stratospheric improvements that the 2nd-gen chip did compared to the original silicon, it’s more than enough to stay ahead of Intel’s flagship chip.

This fits in well with a benchmark spotted back in August. This showed the Threadripper 3000 as having a 3.6GHz base clock and 4.2GHz boost.

The single-core score of 1,275 is pretty much the same as for the current flagship Threadripper 2990WX, and is actually slightly lower than the 1,334 that the Intel i9-9900K scores.

But when it comes to multi-core, the Threadripper 3000’s score of 23,015 absolutely destroys the Threadripper 2990WX’s score of 13,400, and leaves the i9-9900K with its score of 8,726 in its dust.

Some back-of-the-envelope calculations suggest that based on this benchmark that the Threadripper 3000 is some 70% faster than the Threadripper 2990WX. However, as usual, caution is needed when trying to extrapolate benchmark results and translate them into real-world performance.

AMD Readies Three HEDT Chipsets: TRX40, TRX80, and WRX80

AMD is preparing to surprise Intel with its 3rd generation Ryzen Threadripper processors derived from the “Rome” MCM (codenamed “Castle Peak” for the client-platform), that features up to 64 CPU cores, a monolithic 8-channel DDR4 memory interface, and 128 PCIe gen 4.0 lanes. For the HEDT platform, AMD could reconfigure the I/O controller die for two distinct sub-platforms within HEDT – one targeting gamers/enthusiasts, and another targeting the demographic that buys Xeon W processors, including the W-3175X. The gamer/enthusiast-targeted processor line could feature a monolithic 4-channel DDR4 memory interface, and 64 PCI-Express gen 4.0 lanes from the processor socket, and additional lanes from the chipset; while the workstation-targeted processor line could essentially be EPYCs, with a wider memory bus width and more platform PCIe lanes; while retaining drop-in backwards-compatibility with AMD X399 (at the cost of physically narrower memory and PCIe I/O).

To support this diverse line of processors, AMD is coming up with not one, but three new chipsets: TRX40, TRX80, and WRX80. The TRX40 could have a lighter I/O feature-set (similar to the X570), and probably 4-channel memory on the motherboards. The TRX80 and WRX80 could leverage the full I/O of the “Rome” MCM, with 8-channel memory and more than 64 PCIe lanes. We’re not sure what differentiates the TRX80 and WRX80, but we believe motherboards based on the latter will resemble proper workstation boards in form-factors such as SSI, and be made by enterprise motherboard manufacturers such as TYAN. The chipsets made their way to the USB-IF for certification, and were sniffed out by momomo_us. ASUS is ready with its first motherboards based on the TRX40, the Prime TRX40-Pro, and the ROG Strix TRX40-E Gaming.

AMD Sharkstooth Shows Up on Geekbench: Possible Zen 2 Threadripper

AMD is possibly testing its 3rd generation Ryzen Threadripper HEDT processors, with an interesting entry showing up on the Geekbench online database. The entry speaks of an “AMD Sharkstooth” processor with 32 cores and 64 threads, with a nominal clock speed of 3.60 GHz, and the long-form model number “AuthenticAMD Family 23 Model 49 Stepping 0.” None of the 2nd generation EPYC processors correspond with these specs, and so we’re almost certain this is a client-segment Ryzen Threadripper part.

The prototyping platform, which is a motherboard designed in-house by AMD to test the processor’s various components and I/O capabilities, is codenamed “WhiteHavenOC-CP.” In this Geekbench submission, the processor is paired with around 128 GB of memory, and tested on 64-bit Linux. The platform yields a multi-threaded score of 94,772 points, which is about 18.5 percent higher than what a Ryzen Threadripper 2990WX typically manages when tested on Linux. It is also within 5% of what the Xeon W-3175X manages (around 99,000 points). The production model could be clocked higher. AMD will also use the opportunity to launch a new motherboard chipset while maintaining backwards-compatibility with the AMD X399. This new chipset will enable PCI-Express gen 4.0 and come with stiffer CPU VRM and memory/PCIe wiring specifications to enable higher memory clocks and PCIe link stability. AMD is expected to launch its 3rd gen Ryzen Threadripper this October, to preempt Intel’s next HEDT processor series.
