AMD has finally launched two new processors in its 8000-series of APUs, except these ones strictly aren't APUs (Accelerated Processing Units) as the large integrated GPU is completely disabled. That might not seem like they're worth considering but AMD has sweetened the deal by making them its cheapest AM5 socket chips to date.
We first heard tell of these new models, based on the non-chiplet Phoenix 2 architecture, back in March and now we've got a full global launch on our hands. The silicon was originally used for laptops and some handheld PCs, before making an appearance in the desktop PC market in the form of the 8000G series. The best one of those, the Ryzen 7 8700G, is a great way to start the basis of a cheap 1080p gaming PC, although it's a little on the pricey side with a SEP of $329.
| Model | Cores / threads | Boost clock | L3 cache | Integrated GPU | Ryzen AI NPU | SEP |
|---|---|---|---|---|---|---|
| Ryzen 7 8700G | 8 / 16 | 5.1 GHz | 24MB | 12 CU (RDNA 3) | Yes - 16 TOPS | $329 |
| Ryzen 7 7700 | 8 / 16 | 5.3 GHz | 32MB | 2 CU (RNDA 2) | No | $329 |
| Ryzen 7 8700F (new) | 8 / 16 | 5.0 GHz | 24MB | None | Yes - 16 TOPS | $269 |
| Ryzen 5 8600G | 6 / 12 | 5.0 GHz | 16MB | 8 CU (RDNA 3) | Yes - 16 TOPS | $229 |
| Ryzen 5 7500F | 6 / 12 | 5.0 GHz | 32MB | None | No | $179 |
| Ryzen 5 8500G | 6 / 12 | 5.0 GHz | 16MB | 4 CU (RNDA 3) | No | $179 |
| Ryzen 5 8400F (new) | 6 / 12 | 4.7 GHz | 16MB | None | No | $169 |
That's the same price as the Ryzen 7 7700, which only has a very basic GPU, though its higher boost clock speed and larger L3 cache make it a better CPU than the 8700G. The new Ryzen 7 8700F has no GPU whatsoever and has a lower boost clock than the 8700G and 7700, but U31 Gaming it's quite a lot cheaper—its SEP of $269 is $60 less than the other two 8 core processors. And, unlike the Ryzen สล็อต 7 7700, you do get a Wraith Stealth CPU cooler included in the box. It's not a great air cooler, but it will get you up and running.
The issue we found with the 8700G, however, was that it performs noticeably worse than the equivalent chiplet-based CPU when paired with a discrete graphics card. That's going to be the same with the 8700F, and you can mostly blame that lack of L3 cache for the lower frame rates. But a $60 saving is a $60 saving, and you can be up and running without having to fork out for a third-party cooler.
But if that's still too expensive for you, how does $169 sound for a CPU with six cores, 12 threads, and a boost clock of 4.7 GHz? That really is cheap but the problem for the new Ryzen 5 8400F is that the GPU-less Ryzen 5 7500F is only $10 more and it has double the amount of L3 cache and a noticeably higher boost clock.
And it's not like the 8400F uses less power, as all of the above chips in the above table have a TDP of 65 W.
AMD is claiming a performance win over equivalent budget Intel chips from the past two generations, by up to 24% higher frame rates for the 8700F over the Core i5 14400F. Though it's worth noting these are AMD's own cherry-picked results, so we'll see what they look like in independent tests.
The 8700F and 8400F are chips that are likely to have failed the binning process to be 8000G processors, due to manufacturing defects in the GPU. So rather than grinding สล็อต them down and sticking them in the trash can, it's a sensible choice to repackage them as budget offerings.
Well, the 8700F is certainly a good option for a budget-minded PC builder, but the 8400F isn't cheap enough. For the sake of the price of a couple of coffees, you could get the far superior Ryzen 5 8500G or Ryzen 5 7500F. If it was my money, I'd get the 7500F even though its GPU is mediocre compared to the 8500G's.
The latter only has 4 Compute Units, half that in the Steam Deck's chip, so you're pretty much limited to basic or old games, even at 1080p. Sure, you won't be playing any games with the 7500F's GPU but given that it's the more capable CPU of the two (L3 cache helps a lot in games), that's where my money would be heading to.
I can't see AMD releasing any more Zen 4 variants now, as it'll be gearing up ready to launch its forthcoming Zen 5 range for desktop PCs, laptops, workstations, and well, everything really.
