Radeon Pro 555X vs 560X

I’ve seen on the other hand 560X gets 58k points whereas my 460 gets 46k points. This time we’re talking about more than %10 performance increase.
Hey, this is so ridiculous. You’re talking about a laptop costs at least 2500$ and asking for if 90$ gpu upgrade is worth it. OF COURSE it worths. Generally gpus are the most expensive things in laptops to upgrade and the difference is way more than 90$.

He said 10% faster clocks, not 10% faster ;) But those benchmark results are strange. I’d like to see more reliable benchmarks.

geekbench needs an education in statistics.
it might be interesting to dig out the (genuine) imac pro scores and observe whether scores change with cpu core count.

Seems you posted the results of 555x for 560... Anyway a 10% increase in frequency is not bad for a rebranding

it's fixed. Still, the x machines are disproportionately better at certain subtests.

I believe macos can use cpu aswell as gpu for opencl processing, so perhaps this is why results look disproportinately large?

yeah, 3dmark does the same thing so the extra 2 cores are probably contributing to that discrepancy. Hopefully someone does gaming benchmarks soon. My partner and I are still apprehensive about getting 2018's as his 2017 has already had 2 keyboard failures and his macbooks are much cleaner than mine. 2 more cores are very welcomed for Lightroom/PS/FCPX...
 
This may be of interest:

http://browser.geekbench.com/v4/compute/compare/2621966?baseline=2612309

It compares an 8 core imac pro with an 18 core imac pro. Yes, the 18 core machine has a ******** of memory, but it sports the same vega 56 that the 8 core machine has.

On the 18 core machine,
Sobel is 18 percent faster
Histogram is 28 percent faster
RAW is 8 percent faster.


Assuming that both tests were conducted under ideal conditions-- a terrible assumption-- this implies either that
that the opencl drivers are multithreaded throughout.
--or--
that the geekbench opencl tests themselves perform a substantial amount of computation on the cpu.

if either is true, most of the enormous advantage of the 560x over the 560 can be attributed to the macbook's hexacore cpu, and only a small portion can be attributed to the increased gpu clockspeed.

There is one other possibility. The Radeon Pro 560 and 555's memory bandwidth is limited to 81 GB/s. The Radeon Pro 570,575, and 580 read and write at 217 GB/s.
Perhaps the 555x and 560x also use this high speed memory bus, though it's unlikely.

I'm also interested to buy the MBP 2018 with 560X but I'm not sure if this can handle 4K media without background rendering.
I need a smooth workflow and don't want to render the timeline each minute.
Therefore, it would be very nice if we could get some workflow experience instead of final export speeds.

Buy it, try it, return it if it does not satisfy you. Apple gives you the option.
 
I’m gonna get the baseline processor and dGPU this time around. The upgrade to 6 cores is the big jump, 2.2 to 2.9 and a lil extra cache isn’t mind blowing. The dGPU baseline with 4gb is what I wanted, the slightly slower speed I can deal with. This time around I want the coolest and quietest build, last time I maxed 2 things out and regret how much hotter and louder it gets, specially when gaming or editing. RAM I will max however, RAM is always appreciated and there’s little downside.

May snag an eGPU as well, more load off the internals for as much gain or more as I’d get from the higher CPU/GPU anyways:)

Not too burst your bubble, but the upgraded model's i7 is actually closer to an i9 that it is to the baseline i7. The 560X looks like a significant update too :(
