2018 MacBook Pro with Radeon Pro Vega GPUs
Radeon Pro Vega Graphics Coming to MacBook Pro Next Month
Sorry, what? Where? Link?
Ya I'd be pretty annoyed too. As for thermals, they say 60 percent improvement over the 560x. The 560x is about ~2Tflops, so the new chip should be ~3 or so Tflops. Vega 56 is about 8, so this is probably kinda sorta a Vega 28? So maybe a smidge faster than Kaby Lake G with a 6 core cpu to boot. Probably not awful thermal wise, but hard to say since there aren't any other vega chips in this power envelope.

@nanobit Personally am not concerned about having upgraded to the 560x model at all. These new ones are BTOs which I could never afford anyway, and an eGPU negates any performance needs irrespectively.
@detunedradios The new options are:
- Radeon Pro Vega 16
- Radeon Pro Vega 20
Each with 4GB VRAM.
Update: vs. the 560X, the Vega 20 is 60% faster on Cinema 4D per Apple's tests. This is part of one of the footer notes on the MBP showcase webpage.
Yeah, sounds pretty much like the Vega20 GPU. 7nm would also help to get rid of the thermal issues because it'll be much cooler than 12 or 14nm GPUs
Setup: MacBook Pro 2018 15" 2.6GHz Radeon Pro 560X on macOS 10.14 & Windows 10 (Bootcamp); Sonnet eGFX Breakaway Box 350 with a Zotac GTX1080 AMP! Edition

Cheers, pretty exciting but I fear its just Vega in name... still... the Mac line up is looking the most solid and Pro it has in years... I still can't believe people think the 2015 MBP's were great machines when only the top one had any sort of real GPU!
@eightarmedpet I agree about your comment on the 2015s. Sure for some the ports matter I guess, but I personally think 4 TB3 are way superior I/O and with Quad-Core 13" the MBP lineup seems stronger (and pricier) than ever.
@nanobit 7nm makes sense honestly.
@thread So basically they are handsomely nuked Vegas.
Off-topic, fun fact about the new iPad Pros:
Given the last generation iPad Pros approximately performed at about 9300-9400 on Geekbench, a theoretical 90% boost implies scores of 17K+ roughly on the new iPads, which is equal or faster than the 2017 15" MBP. Don't know about sustained loads, but Apple sure knows their silicon. With 8-Core (4+4) CPUs, perhaps it could be an indicator of what kind of hardware setup Apple thinks is the future, even for their Macs. With the vastly higher cooling and space afforded on the MBPs vs. the iPads, they could do some serious shit.
Looks like the Pro Vega 16 and 20 are 14nm parts. We will have portable heaters really soon.
Anyway, IIRC the TDPs on the current dGPUs in MBPs is 35W, and I doubt that’s changing. So a Vega at 35W. Apple is really squeezing out the performance per watt somehow if the gains over the 560x are up to 60% (at least on Cinema 4D).
What Nvidia gpus are these Vegas comparable to?
@eightarmedpet Not sure but let’s take one metric: OpenCL. On Geekbench a 1050 Ti in the XPS at maximum performance scores about 85k. The MBP’s 560X does 60k consistently. Taking the best case of 60% performance improvement, the Vega 20 would score 96k, placing it above the 1050 Ti easily. For reference, an RX 480 would score 120K, and an R9 Fury does about 100K (poorly optimized drivers on macOS I guess). IIRC on High Sierra even the 1070 does 120K or thereabouts (need to recheck this).
But, assuming 30% average performance improvement, we would see 78K on the Vega 20. Worth noting that AMDs typically fair better in compute than NVIDIA, esp. on macOS. I guess it’s fair to say it may perform similar to a 1050 Ti in general (but may do better for compute tasks and Metal) but at less TDP. This is back-of-the-envelope stuff so take it with a grain of salt.
Cheers for the guesstimating... nice to see Apple taking GPU power a bit more seriously, although 1050ti is hardly a heavy hitter, and if I had just bought a 560x equipped MBP I Don't think this would phase me as I expect these to be very expensive BTO options and nowhere near as powerful as a basic eGPU still.
@eightarmedpet Precisely. We have to keep in mind that it's the same chassis/cooling so all improvements will fall down to Vega efficiency at lower clocks/CUs, unless these options have a tweaked cooling system - we never know: The 1TB iPad Pro has 6GB RAM while the rest of the options have 4 - so they might do something. The only impressive thing I suppose is the performance per watt as has usually been the case with the MBP dGPUs.
