![]() ![]() Top 10 Suppliers Series – European Survey.AMD posted an interview containing some nice details, AMD confirms that the first Zen 3 CPUs with stacked 3D V-Cache will be. It's been five years that the first Ryzen processors have been released. In Geekbench some scores leaked, and while we don't trust geekbench scores, the specs however are listed in great detail. .ĪMD Zen 3 processors with 3D V-Cache in early 2022, then Zen 4 later that year with PCIe 5.0 and DDR5. On Twitter Petykemano discovered the unknown 5nm chip in the OpenBenchmarking database.ĪMD Zen 4 Based Genoa CPUs Get 1 MB L2 Cache per Core - 03:47 PMĪnd that's a lot. Performance places the processor approximately 17% ahead of an equivalently clocked 128 cor.ĪMD Zen 4 CPU with 5.2 GHz Boost and RDNA 2 iGPU surfaces - 09:17 AMĪMD's upcoming Ryzen 7000 (Raphael) processor is exposed. The Socket AM5 package is used to build "Raphael." AMD is said to be working on a small BGA packaging of "Raphael" for high-performance notebook platforms, dubbed "Dragon Range." These CPUs will be available in 45 W, 55 W, and 65 W TDP configurations, and will power high-end gaming notebooks.Ĭinebench R20 Score for AMD Zen 4 Ryzen 7 7700X Processor Leaked - 09:16 AMĮxtreme Player, a tech news publication on Bili Bili, apparently leaked the Cinebench R20 score of an AMD Ryzen 7 7700X Zen 4 processor (probably engineering sample).ĪMD Zen 4 EPYC CPU Benchmarked - 17% Single Thread Performance Increase (192-core, 384-thread) - 08:55 AMĪn EPYC 9664 appears on Geekbench 5 in a dual-socket configuration for a total of 192 cores and 384 threads. The multi-chip module Raphael contains one CCD for the 6-core and 8-core SKUs and two CCDs for the 12-core and 16-core SKUs. The new 6 nm cIOD measures 124.7 mm2, which is somewhat larger than the Ryzen 5000 series' 124.9 mm2 cIOD. Aside from DDR5 memory controllers and a PCI-Express Gen 5 root complex, this cIOD includes an iGPU based on the RDNA2 graphics architecture. Certain power-management capabilities from the Ryzen 6000 "Rembrandt" processors are also included. It's manufactured on the 6 nm (TSMC N6) node, which is a significant improvement over the GlobalFoundries 12 nm node used for the cIOD of Ryzen 5000 series processors. The "Zen 4" CCD has 6.57 billion transistors, a 58 percent increase over the "Zen 3" CCD's 4.15 billion transistors.The cIOD (client I/O die) is seeing a lot of innovation. The CCD is 70 mm2 in size, unlike the 83 mm2 Zen 3"CCD. Because of the transition to 5 nm, the Zen 4 CCD is slightly smaller than the Zen 3 CCD despite having more transistors (TSMC N5 process). The size of the L1 branch target buffer (BTB) has been raised from 1 KB to 1.5 KB. The dispatch stage's reorder buffer (ROB) has been increased from 256 to 320 entries. The shared 元 cache's latency has also increased, from 46 to 50 cycles. The expansion of the L2 cache increased latency somewhat, from 12 to 14. The L1I and L1D caches remain 32 KB each, whereas the L2 cache has more than doubled in size. AMD's Mark Papermaster announced at the Ryzen 7000 launch event that the company has increased the core's micro-op cache from 4 K entries to 6.75 K entries. Chiakokhua (aka Retired Engineer) posted a table comparing the latencies of the various caches to those of the "Zen 3" core. ![]()
