AMD Ryzen 7 8700G CPU-Z Results Puts it Neck and Neck with the Ryzen 7 7800X3D

[TheLostSwede]

The first CPU-Z test results of AMD's upcoming Ryzen 7 8700G were sniffed out by serial leaker @momomo_us on X/Twitter and the new APU is looking very promising performance wise. It ends up being neck and neck with yours truly own Ryzen 7 7800X3D with a small lead to the CPU over the APU in single-threaded performance, but in the multi-threaded test the APU manages to stay ahead of the CPU, if only just. Both AMD chips are still somewhat behind Intel's Core i7-12700KF, but it has an extra four threads, even though those threads are slower due to them being on the E-cores.

The Ryzen 7 8700G test system was using an ASRock B650 Pro RS motherboard and the APU was paired with 32 GB of DDR5-6400 memory with reasonably tight timings of 32-39-39-102. The tester relied on the integrated Radeon 780M graphics in the APU and the Windows 11 operating system was installed on a 500 GB Seagate BarraCuda 510 SSD. In the single-threaded test the Ryzen 7 8700G scores 675 points vs 683 for the Ryzen 7 7800X3D and in the multi-threaded tests it came in at 7318 vs 7301. Not bad for a 65 W TDP APU vs a 120 W TDP CPU. For comparison, the average for Intel's Core i7-12700KF is 7754 in the mutli-threaded test. Although CPU-Z is far from an exhaustive test, it does at least give us a first glimpse of what to expect from the new Zen 4 APUs from AMD in terms of performance and it looks like it's in line with its best Zen 4 CPUs.

That is good news but also what I would expect! Its the same base core design without the X3d Cache.

Two things. How much does the X3d cache benefit this particular benchmark? I assume near nothing?

How good is the APU in gaming?

If decent/good this may be a great way of getting a HTPC/1080p/Console replacement for a decent price with the capability of being able to expand at a later date. The need for the ewaste GPUs (think Nvidia xx50/AMD x500 and lower) becomes even less.

I doubt x3D does much in that benchmark.

The 8700G should be clocking higher so that could explain the results, in gaming centric scenarios I expect the big cache to win hands down.

No idea, but I think so. It was more that the two happen to be within 25 MHz of each other and I obviously had my own results at hand and it was easy to compare the two.
The base clock is the same and the max boost is a mere 100 MHz higher for the APU, so it's a pretty fair comparison.
That said, I re-ran CPU-Z just now and the X3D is now only 4 points behind in the multi-threaded test, but this is obviously going to vary a bit between systems.

No idea, that will be one of the things we'll find out from the reviews.

The only downside is that it's limited to a PCIe x8 interface for the x16 slot, but it might not matter too much, since in the tests done here at TPU to compare PCIe scaling on different graphics cards, it tends to be within 1-2% to go from x8 to x16. Also, no PCIe 5.0, but again, might not matter much.

I don't think Zen 4 scale well with power over a certain point so that might explain why the 8700G is so close. I also suspect that Zen 4 wit a beefer L2 cache is probably less sensitive to the L3 cache reduction than Zen 3. It's possible that with good boost clock and by not having to do chiplets to chiplets communications, that the memory latency could be good.

I still think X3D would have the lead in most gaming workload.

But APU/Mobile chip CPU performance have been more than enough for quite some time. What would move the needle is much better iGPU performance. Something that could do good 1080p high in recent game would be amazing. we will see what AMD have in the roadmap.

I'm guessing those results are from mobile parts using up to ~50W.

I would just check 7840HS gaming results, they should perform within 5-10% of each other, literally the same cpu, just different thermal and power budget.

8k series already

I bought 1k series July 2017 then 5k series Dec 2022. Going to be past the 9k series before Dec 2027.

Tbf, the middle or every second series is either a refresh of the same architecture or a gimped version of the previous series, to technically, just 4 architecture here.

Ya and the 4k series went to oems as well.

Either way, I will be sticking to my 5+ years upgrade cycle. So see what's available come summer 2028.

Still pretty good for integrated graphics . At least it can provide 1080p gaming and cpu duties for $330. This would be great in a tiny portable enclosure that can be tucked behind a monitor or thrown in a backpack etc

True but misleading results, especially with some specs like TDP. 7800X3D effectively runs into power limit at 75-85W, usually 76-77W. If previous generations are any indicator, 8700G with its 65W TDP will boost at least to 90W but more likely to the usual 120-140W range.

7800X3D will have frequency advantage unless it runs into power limit and it has hell of a cache advantage with 8700G still sporting 16MB. In games, it'll leave 8700G in dust, even before all the PCIe lane shenanigans and such come into play. 8700G will fare even worse against 7000 series because of same or worse frequency disadvantage, 7000 series has 32GB cache and runs at same power limits.

And yet Hardware Unboxed shows it to be slower than 7700. I didn't realise 7700 (not 7700X) was slower than 7800X3D in productivity.

7700/7800x3d are the same core counts etc just the cache is different.

Yes the 7800x3d has more power limits but it has a lower boost clock set due to temperature sensitive on the 3d cache.

I'm confused why a 2+ generation old Intel CPU is being used as a comparison. Is it because they are in the same price bracket ? Also the 8700G is best used in a micro build. I mean it loses miserably to an i3 and 6500/6600 combo that's cheaper than the 8700G itself. I'm always confused why these CPU companies put themselves in these circumstances. I suppose it's because people keep buying the stuff.

I know cpu-z doesn't matter much, but I just gave it a whirl and I score higher in single and multi than the guru3d review and the numbers listed here in this news post. So, that is cool at least I am where I should be with this chip.
