AMD Ryzen 7 5700G

[W1zzard]

With the Ryzen 7 5700G, AMD is finally bringing their most powerful APU to the retail DIY channel. With 512 graphics cores based on the Vega architecture, the IGP is over twice as fast as Intel's Rocket Lake graphics. Thanks to the Zen 3 architecture, the eight CPU cores are blazing fast, too.

Have I read this correctly? All 20 PCI Express lanes from the CPU are available (albeit in GEN 3), unlike the 3400G which only had 12 available? And does that mean that 4x4x4x4 bifurcation is available for the primary PCI Express x16 slot?

 

[W1zzard]

bifurcation

doubt it

Was there only 512MB addressable to the iGPU? Do you think iGPU performance will change if more memory is allocated to it?

Great idea, let me test that

 

[damric]

Also the slide that says DDR4-4266 possible on the new memory controller. I'd love to see you test that if you have any kits available to see how performance of the IGP scales.

@W1zzard, any plans for doing a clock-for-clock comparison between 5700G and 5800X - or maybe 5600G and 5600X since these are more closely matched out of the box?

Was there only 512MB addressable to the iGPU? Do you think iGPU performance will change if more memory is allocated to it?

Quite sure more is addressable to iGPU and the amount of RAM allocated to iGPU does not affect performance (other than scenarios with running out of it of course). At least based on how this worked with old 2400G and 5700G should not that much different when it comes to iGPU.

Yup, I think so too, still something worth verifying

Great review, seems like a solid product just need to get rid of the Vega iGPU and move to RDNA.

"The problem is that for 1080p gaming, the integrated graphics are simply not powerful enough, not even at the lowest possible setting. For pure gaming, you'll be better off with a several year old graphics card (that supports DirectX 12), paired with a value-champ CPU like Core i5-11400F, Ryzen 3 3300X, or 10400F, in that order. These CPUs go for around $170, which frees up $200 for a graphics card."

^ Yeah this has always been the problem with 'premium' priced APU's. $360 is almost 3-4x the price that the 3200G / 3400G were and makes little sense for budget gamers vs buying a cheaper CPU + GPU unless they really want to pay through the nose for a niche slim ITX build in a case like the Inwin Chopin. I bought an i5-10400F for £124 and GTX1660 for £159 (total £283) with 4-5x the performance and certainly wouldn't spend anywhere near the same money on "between GT1030 and GTX1050" class performance (which is what this APU has) vs simply buying a cheap 1050Ti / 1060 on Ebay. MOAR CORES doesn't do a thing for low-end gaming with such strong GPU bottlenecks, you just sit there with impressively low CPU usage to match the impressively low frame-rates (20-50fps at 1080p in most games here). And budget gamers tend to not have 3800 speed RAM lying around so either more money on top for a possible RAM upgrade (or lower performance for typical budget 2666-3200 modules) needs to be factored too. What would have been interesting is if AMD had released a cheap 5300G for the same price as the 3200G (£79 at one point) during the worst of the GPU shortages, but they're refusing to sell that even now (outside of OEM), so even after 2-3 years there's still no real "upgrade" to the 3200G / 3400G at anywhere near the same price point. People who can't afford £80 CPU's + £150 GPU's tend to not buy +£300 APU's with half the performance...

Yes that's exactly how it works. The iGPU "memory size" is just the "window" the game sees. If a game needs 2GB VRAM but you have it set to 512MB VRAM, then it will use +1.5GB more from regular RAM instead of VRAM (which for iGPU's is the same thing). ie, if a game uses say 2GB VRAM and 3GB system RAM, and you lower APU "VRAM" size from 2GB to 512MB in the BIOS, it will appear to use only 512MB VRAM in MSI Afterburner, etc, but the 3GB system RAM will increase to 4.5GB RAM as more system RAM gets used as an "overflow".

"As long as you have any half-decent CPU cooler, then you'll have no problems keeping the 5700G cool. This makes AMD's new APUs an excellent choice for compact small form factor ITX systems."

I have a feeling that I'll have to test that claim sometime in the future. So far, my experience with Ryzen (except the 3100) in SFF builds with limited airflow has been pretty poor - hence my build log, link in my signature. Even the 3600 I tried once nearly overheated in my Aerocool CS-101 case with the factory cooler. Slapping a be quiet! Shadow Rock LP helped a little, but not much. Ryzen CPUs are great if you have that half-decent cooler and a case with good airflow. I'm really curious about the APUs in similar situations. My theory is that the monolithic die should help with heat distribution a little, but as I said: I'll probably have to test it. (just don't know when, as I don't really have spare 400 bucks at the moment)

Talking about energy efficiency: if the integrated GPU is all you are going to use- consider getting 5600G/5700G with an ASRock Deskmini X300. Those systems run the APU as a SoC, without a chipset- thus have stupidly low power consumption: just over 10W idle, compared to ~50W as tested here.

 

[W1zzard]

Benchmark results at 2 GB for IGP have been added, no change

 

[mechtech]

Yes. I have a 3400G on a B550 motherboard and I have it set to 8GB. (32GB system ram)

You are awesome. Thank you for re-running the tests.

 

[mechtech]

Nice review W1zz. The comparison with the GT1030 was good. I think the only thing that would have been better would be to compare igp to 3400G.

 

[Chrispy_]

The point of the 5700G is for the IGP, but Vega8 is so dated and shit that it's pointless.

I bought a budget 2500U with dual-channel DDR4-2400 for Christmas in 2017 and almost 4 years later all AMD's can be bothered to put in their top end APU is the same shit but clocked about 60% higher. The only difference is faster DDR4 is now available and a desktop socket gets more power budget to play with.

RDNA APUs already exist in AMD's lineup but us DIY consumers get the left-overs and scrapings!

 

[defaultluser]

Having nearly 1050 performance in an IGP in an impressive achievement. If my GTX 960-powered HTPC suddenly died, on me, I would just replace it with the 5600g.

The cut cache does affect some games, but you still get a noticeable memory controller latency bump over Zen 2 (i.e. all games are faster than 3800xt.)

Agreed. Shame that the 5300G isn't coming to DIY. That would be the ideal HTPC part. Both the 5600G and 5700G are overpowered and too expensive for such use.

But that can't run Zen 3 (so you're stuck going fishing for a not-really-existing Zen 2). Asrock cant be bothered to update the chipset to A520

I disagree. By the time you cut Vega down to 6 cores, the performance is closer to a 1030, and also if you run any kind of emulation, 4-cores is the bare-minimum for doing anything more modern than ps2/Gamecube.

$360 for 5700G is just too much if you're building gaming PC. You can opt for GTX 1650 + 10400F or 2nd hand 570 4gb + 10700F combo around the same budget and have much better gaming experience.

AMD needs to offer Zen3 + 12 or 16 CU RDNA1/2 APU to make me interested.

You are probably mistaking this with A300? The newer X300 has 5700G/5600G in their official supported CPU list.
Also- A520 is an actual chipset(chip), which these systems do not physically have, but run everything from the APU. And the mentioned 10W power use would no longer be there with A520, B550, etc. chipsets.

With that superb power efficiency, this is the ITX build king.

I dont think people buy these only for serious gaming. For a multimedia or productivity machine yes, or esports maybe. In which case a huge 1650 in your itx case is unnecessary.

I agree. This APU is great for something like HTPC. But I hoped AMD would offer us 12 and 16CU APUs by now. Let's hope we get them with Zen4+RDNA2/3 and DDR5 APU combo. Such APUs should rival 1060/580 level of performance and make APUs truly viable option for 1080p/60Hz gamers without the need to take much compromises.

It is not as simple as putting more CUs in the iGPU. Desktop DDR4 is just not fast enough to feed more CUs.
This is why AMD went from 11CUs down to 8CUs, as the overclockers have shown that the 3CUs offers almost no performance.
RDNA2 requires a big cache, and the APU just do not have enough free die space for it, thus they even cut down the CPU cache from Zen3 CPUs.
