AMD Strix Point “Ryzen 9” APU With 12 Zen 5 Cores, 24 MB L3 Cache Spotted, Impressive Multi-Core Score Despite 1.4 GHz ES Clock

AMD Strix Point "Ryzen 9" APU With 12 Zen 5 Cores, 24 MB L3 Cache Spotted, Impressive Multi-Core Score Despite 1.4 GHz ES Clock 1

An engineering sample of AMD's Zen 5-based Strix Point "Ryzen 9" APU with 12 cores, 24 threads, and 24 MB of L3 cache has been spotted at Geekbench.

The engineering sample was spotted within the Geekbench database and has the specific OPN ID of "100-000000994-14_N". This ID can be confirmed as an AMD Strix Point APU since it has already shown up multiple times, once last year in the MilkyWay@home database and more recently in the shipping manifestos which pointed it out as a Strix Point (1) chip rated at a TDP of 28W & designed for the FP8 platform for mobility platforms.

The CPU was running on a Xen Virtual Machine and it should be pointed out that due to the early nature of the chip and little support within the Geekbench database, most of the details are either missing or not correctly pointed out. The chip is correctly identified as an "AuthenticAMD Family 26 Model 32 Stepping 0" part.

AMD Strix Point "Ryzen" APU - 12 Cores @ 1.4 GHz:

AMD Strix Point "Ryzen" APU - 12 Cores @ 2.0 GHz:

To start, the AMD Strix Point "Ryzen 9" APU features a total of 12 cores based on the Zen 5 core architecture with 24 threads. This is the fastest configuration that we will see for Strix Point (1) SKUs. The chip is listed with 16 MB of L3 cache and 1 MB of L2 cache but we know that there's a mix of Zen 5 and Zen 5C cores which means that this is only the Zen 5 (classic) core count listed. The chip itself should feature a total of 24 MB L3 cache.

As for the L2 cache, it should be the same across all cores so 12 MB of L2 (1 per core). Furthermore, the L1 Instruction cache is listed at 32 KB while the L1 data cache is listed at 48 KB. The data cache has seen a 50% bump versus Zen 4 cores while the instruction cache remains the same.

The AMD Strix Point "Ryzen 9" APU is listed with a core clock of 2.00 GHz but the log file shows that the chip only ever reached up to 1.4 GHz clock speeds which isn't by any way reflective of the final model. These are super early ES clocks and we should expect the chip to go up to 5 GHz or beyond when the final silicon shows up. With that said, the chip scored 1217 points in single-core & a very good 8016 points in the multi-core CPU test.

The second test has also been leaked at 2.0 GHz and shows an even better performance than the previous result. The APU was tested on the Birman Plus-STX reference platform. Birman is the FP8 reference evaluation platform that was previously used to test Phoenix & Hawk Point APUs.

For comparison, the AMD Ryzen 9 8845HS with 8 Zen 4 cores currently scores around 12,000 points and that chip runs at up to 5.2 GHz clock speeds. So 12 Zen 5 cores running at similar clock speeds should deliver some huge multi-threaded improvements and we can also expect big single-thread gains.

Following is the full summary of today's leak:

AMD Strix Point (1) ES APU

FP8 Platform / 28W Design

CPU Family: AuthenticAMD Family 26 Model 32 Stepping 0

CPU ID: 100-000000994-14_N

12 Cores / 24 Threads (Zen 5 + Zen 5C)

48 KB L1d / 32 KB L1i / 1 MB L2 (per core) / 24 MB L3 (Total)

2.00 GHz Clock (1.4 GHz actual peak) ES

Zen 5 is a brand new architecture and it should come with some nice IPC gains over the existing Zen 4 CPUs. With that said, AMD's Strix Point APUs are expected to launch later this year with Strix Point (1) rolling out first for mobility platforms followed by the chiplet-based premium chips which will offer higher core counts on both CPU and GPU. Expect more info on the AMD Strix Point family at Computex 2024.
