AMD has already unveiled its latest Ryzen AI 400 desktop processors. These new Zen 5 chips are available exclusively to OEMs, but they still compete with today's best CPUs. Early benchmarks for the Ryzen AI 5 435G, shared by Gray, indicate that the Ryzen AI 400 series is on the verge of release and could shake up the budget desktop market.

Gorgon Point tops out with eight Zen 5 cores, and an integrated Radeon 860M engine featuring eight compute units (CUs). AMD designed Gorgon Point with flexible TDP options of 35W and 65W to accommodate a range of system builds from compact desktops to more demanding professional systems.

The Ryzen AI 5 435G is the entry-level SKU in the Gorgon Point lineup and features a familiar six-core, 12-thread configuration. The chip rivals the existing Ryzen 5 8600G (codenamed Phoenix), which has a similar setup but on the older Zen 4 cores. Although it has six cores, the Ryzen AI 5 435G has two Zen 5 cores and four Zen 5c cores. Likewise, the Ryzen 5 8500G leverages two Zen 4 cores and four Zen 4c cores.

The Ryzen 5 8600G has substantially higher clock speeds. Presumably, this is due to the OEM focus on Gorgon Point. In any event, Zen 5's 16% IPC improvement over Zen 4 balances out the equation. When you have a significant architectural leap, for example, a Zen 5 chip with a 500 MHz lower clock speed can still outperform a Zen 4 chip.

There's a big difference between the Ryzen AI 5 435G and the Ryzen 5 8600G's graphics capabilities, too. Although the former is on the faster RDNA 3.5 graphics, the latter has double the CUs, so it's still faster despite the CUs coming from RDNA 3. In gaming, the Ryzen 5 8600G should have the upper hand. Perhaps the biggest upgrade on the Ryzen AI 5 435G is its beefed-up NPU, which delivers more than 3X the AI performance of the Ryzen 5 8600G.

Hardware detective Gray recently uncovered two Geekbench 6 submissions for the Ryzen AI 5 435G, giving us a taste of the Zen 5 chip’s real-world performance. Analyzing the top scores from both entries, the Ryzen AI 5 435G achieves scores of 2,620 points in the single-core test and 10,718 points in the multi-core test. For context, the Ryzen AI 5 435G outpaces the popular Ryzen 5 8600G (2,492 points and 10,857 points) by about 5% in single-core performance and is only marginally behind, approximately 1% slower, than the Ryzen 5 8600G in multi-core performance.

The narrow performance gap between the Ryzen AI 5 435G and Ryzen 5 8600G demonstrates the power efficiency Zen 5 brings to the table. However, it should be interesting to see the Ryzen AI 5 435G's full potential outside of a single benchmark. Luckily, we won't have to wait long, since Ryzen AI 400 desktop systems should start hitting the retail market in the second quarter of the year.

Update: Corrected typo with Ryzen 5 8500G.

    Even L3 cache is cut in half on the 435G, so they really aren't direct siblings. I'm wondering if there will be a faster Ryzen AI 5 model that's actually a more direct successor to the 8600G, i.e. less cut-down.

    There are quite a few errors in the specs for the R5 8600G (Phoenix), as it doesn't have Zen4c cores. It only has 6/12 regular Zen4 cores, albeit with reduced L3 cache. The 8500G (Phoenix 2) does have both Zen4 and Zen4c cores, in addition to the Radeon 740M, which is similar to a rehashed version of the Ryzen 5 435G.

    The Ryzen AI 5 440G gets 3+3 cores and 16 MiB L3 instead of 2+4 and 8 MiB. I don't care for Geekbench, but the 440G should be close in performance.

    On graphics, it's 8 CUs RDNA3 vs. 4 CUs RDNA3.5 for the 435G/440G.

    The current top Ryzen AI 7 450G based on the full Krackan die gets 4+4 cores, 16 MiB, and 8 CUs RDNA3.5.

    That chip will be superior to the 8600G, and possibly do better than expected against the 8700G, since the 8700G's 8 cores and 12 CUs may be more power and bandwidth constrained.

    AMD needs to release Strix Point if they want to actually dethrone the 8700G. Anything based on the Ryzen AI 9 365 should already be a little faster than the 8700G, with the Ryzen AI 9 HX 370 with the full die delivering more substantial improvements.

    Even if that doesn't happen, hopefully these Krackan desktop APUs end up being pretty cheap. They will certainly have decent CPU performance.

    It would be great if we could have power consumption figures.
    The 2GHz min clock of the 435 could mean a noticeable reduction of idle and average power already, which combined with the more advanced node could favorably boost efficiency over the 8600G.
    I think these are quite useful metrics to look at.
