News AMD Ryzen 4000 APUs May Feature Vega 12, Vega 15 Graphics

Please, AMD, I'm begging you, match up the APU numbering scheme with the generation of CPU they go with.

If you have to, call the APUs based on the actual Zen 2 (ie: first 7nm architecture) the 3x30G series or something.

Then when there are APUs based on the 4000 Ryzen, call them the 4x00G series, the ones based on the 5000 Ryzen the 5000G series, etc.

There's no good reason for this weird mismatch.

A new APU with HBM would be more interesting. The DDR4 memory is the real bottleneck here. Looks at benchmark of GTX 1660 Super, memory matters a lot when it comes to GPU performance.

But its not feasable.
Hbm isn't small, and adding it to a cpu would take up space.
Sure it is. The 8GB of HBM2 on Vega56/64 are pretty tiny, (each 2 x 4GB dies about 100sq mm), there is more than enough room for one (4GB) in a one-chiplet (or even 2 chiplet) CPU.

RX 560, maybe. No way you're getting 570 level performance. The article talks about 13/15 CU iGPU configs. The 570 has 32 CUs.
Vega can run much higher clock speed than polaris though, so there's a possibility that a 15cu vega can perform at least close to an rx 470 or gtx 1650

I'm only seeing a couple hundred MHz difference between Vega 56/64 and Polaris chips like the 470/570. Given that a 15 CU GPU would have less than half the resources, it'd have to have at least twice the clock speed to have a chance at matching performance.

Edit: and of course memory bandwidth would still be massively lower compared to a proper dGPU with GDDR[X] memory.

Adding HBM would increase the price considerably. However, if the performance justifies it I'd pay. I'm saving money and waiting for a good all-around APU from AMD. Four ZEN2 cores with SMT is enough. It's the iGPU part that's unsatisfactory. AMD should make something like Kaby Lake-G processors, but not in BGA package.

While its not exactly entirely straightforward, the fact is, the vast majority those buying these processors probably won't care, as they are not really targeted at the "performance" market. These are lower-end processors for more budget-oriented systems. If someone is after optimum gaming performance, they should probably be looking at something else. The vast majority also won't even have any clue about AMD's Zen 2 architecture offering IPC improvements, or Navi for that matter. The only ones who might care are those following tech hardware releases, and they will know for that reason, so it's a bit questionable how much it actually matters.

Even with HBM, these APUs would have limited graphics performance, since they just don't have enough graphics cores to compete even with lower mid-range parts. Maybe this rumored Vega 15 APU could get up around RX 560 / GTX 1050 level performance with HBM memory, but those were fairly low-end graphics cards even when they launched a few years ago, and you can get nearly double the graphics performance out a dedicated Radeon RX 570 for as little as $130 now, and there may be even more performance available in the budget range once AMD fills out their RX 5000-series lineup.

On that note, you probably wouldn't be saving much going with an APU with onboard HBM2 memory. I don't know about current pricing, but a couple years back when Vega launched it was around $150 for 8GB of HBM2. It's probably less now, but still might raise the price of a $150 APU to something closer to $250. And you would still likely be getting far less performance than one of those $130 RX 570s combined with a $120 Ryzen 2600. With graphics hardware in this performance range, Zen 2 isn't going to matter as much, since any recent games are far more likely to be graphics limited than CPU limited, even with the previous-gen Ryzen parts. Having those additional cores and threads will likely be beneficial down the line as well, since games are becoming more heavily multithreaded, and next-year's consoles will apparently be utilizing 8-core, 16-thread processors.
