CPU AMD APU Raven readying for launch
- Thread starter stree
- Start date
Okay. Let's say you need 80-100% more performance to meet 1050 class.
- from 8 to 11 compute unit should net you a linear increase of 30% more performance.
- from around 500mhz sustained clocks to 1100-1300 mhz should get you 50%
- more bandwidth RAM should also get you 10%
I think we can see 750 TI to 1050 level of performance.
My original comment wanted to point out that is a very low power chip. It's heavily power throttled. I'm quite amazed that it can almost match a MX150 despite having a CPU and being reliant on RAM speeds.
If you are talking about pure compute power, it's likely that AMD could get something close to the 750 with 11 CU. It's going to take the Fenghuang and 28CU with HBM2 to get to the GTX 1050 levels or better if meaning frame rates in gaming. Keep in mind that AMD has a graphics chip with 16CU at 1275mhz plus boost and 7000mhz GDDR5 and it's barely competitive with the 1050, and has a 75w TDP. I am hoping AMD can put something impressive together but I've been saying this for about a year now, unless AMD gets a solution for the memory bandwidth limits (HBM), the gaming performance of the APU is going to stay far below the 1050.
The fenghuang is the only thing I've seen so far that could get there.

The 560 is very competitive, not barely. It trade blows with the 1050. Winning in Vulkan and compute heavy titles. Loses to Directx 11 titles.
Though I do concede that the 11 CU will not be 1050 level. There are still rumors of a desktop 16 CU, so there is hope for a 750 ti to 1050 class graphics.
I think I've read somewhere that having the CPU and GPU on the same chip can reduce certain latencies and improve performance beyond what you would expect from the equivalent powered discreet GPU and CPU, whether this is true or not I don't know.
Hardware Unboxed have recently done a video benchmarking the Ryzen 5 2500U in the HP Envy x360 which has the APU configured at 25W TDP (when plugged into the wall). The gaming performance is impressive being able to average 32 FPS @ 1080p in Metro Last Light medium settings, that's not bad considering its 25W TDP. For comparison from other reviews the mobile GTX 965M gets around 63 FPS @ 1080p Medium, and a GTX 750Ti + 4670K@3.4GHz gets around 53 FPS @ 1080p Medium.
Not sure how this would scale up when going from 25w > 65W (and maybe 95W K chips?), but maybe we can expect something in the region of 250% better performance for the 65W desktop versions?

95w is totally possible, and with AMDs proven track record of doubling performance when doubling power consumption....Oh wait my mistake.

The 2500U in gaming tests is at a large deficit against the 8250U + MX150 and from what I have read, despite being 15W TDP it's about equal to the 15 + 30W on the 8250u + MX150 on actual battery life. The gaming performance could be from the CPU throttling (AMD needs to do better in power management), and it could be from DDR4 vs GDDR5 (so again, AMD needs to figure out a solution to the memory bandwidth issue) - but either way I don't think its realistic to expect AMD is going to get 2-3x better performance on the desktop APU just because of it having a higher TDP. If AMD is going to cram more CU's on the chip, they can definitely get much better performance, but as already mentioned it's a pretty full chip as it is.
Something around the MX150/GT1030 is likely for most desktop APU's (with stronger GPU compute power but equal gaming performance) but GTX 1050 would only be attainable with the rumored configuration for Fenghuang (including the HBM2). I really hope Fenghuang is real and it can make it onto the AM4 socket.

This is actually pretty promising so far. He definitely had some set up woes and was only able to get 2666 in the ram but impressive early results. This is enough for casual gaming and these will fly off the shelves. The GPU state of affairs adds even more incentive to start with a RyzenG platform for budget builds. Play now and chuck in a midrange gpu later for an easy upgrade. Same argument as the Kaveri APU but the Ryzen CPU actually won’t bottleneck your DGPU down the line.
Yea I wonder what performance will look like with a proper driver and a decent OC. I also wonder if there is a possibility of a dual graphics solution with a 550-560? I know dual graphics was pretty disappointing with the last APUs but maybe the performance of this one will help. What my dream would be is an OCed Ryzen 5 2400G paired with a 560 low profile gpu performing between a 1050 ti and 1060.
Dual graphics is dead. Drivers never worked anyways, and if you're getting dual graphics, you might as well just get the 2200G + 1050 ti for the same price.
An another note, I'm much more interested in the 2200G. At 60% of the price, it hits a much nicer price point.
The problem with any sort of dual graphics, be it SLI, CF or MDA is QA. If you have N cards you need to test the single card part of your software then you need to test roughly square of that for the dual part. You are supporting 20 different video chipsets? Great! Now you have 190 pairs to test. It's too daunting to even try.
NDA will more than likely end at 2pm GMT, I'd expect reviews and availability to appear then.
After doing more research it does appear that the Ryzen APUs do not support dual graphics. So it’s just down to how these APUs preform overclocked. Hoping to see that in reviews later on today.
I wonder if that may be due to the fact it has twice the CPU power of the G4560. Also due note that the G4560 does not have boost so it may be clocked closer to it's optimal speed.
I'm sure with a little bit of tuning the CPU side you can trim a bit more power, but likely to never reach the efficiency of a G4560.
