High-End Retina 5K iMac Benchmarked Faster Than Low-End Mac Pro

Yesterday, Primate Labs highlighted some Geekbench 3 benchmarking results for the new 3.5 GHz 27-inch Retina 5K iMac, unsurprisingly showing the machine performing better than slower-clocked Core i5 chips in non-Retina models but below that of high-end Core i7 chips also available in the machines since their late 2013 introduction.

Primate Labs' John Poole noted that once benchmarks for the high-end Retina 5K iMac with Intel's 4.0 GHz Core i7-4790K chip started appearing, they could show the new iMac outperforming the low-end Mac Pro, and that is indeed the case as revealed today and highlighted in an updated version of Poole's blog post from yesterday.

The 4.0 GHz Retina 5K iMac clocks in with a score of 4438 on the single-core 64-bit benchmarking test, while multi-core testing achieves a score of 16407. Across the two tests, the new high-end Retina iMac scores 11-13 percent higher than the fastest non-Retina model due to the faster processor included on the Retina model.

Compared to the low-end Mac Pro, which runs on a quad-core 3.7 GHz Xeon E5-1620 v2, the high-end Retina iMac clocks in over 13 percent higher on multi-core testing, although it is unsurprisingly outclassed by higher-level Mac Pro models carrying processors with more cores.

retina_imac 4_0_mac_pro_bench
Both Retina iMac processor options outperform all Mac Pro models on single-core benchmarks, but this is unsurprising as the Xeon processors used in the Mac Pro sacrifice single-core clock speed for many more cores and other benefits that enhance performance for professional-level applications that can take advantage of the multiple cores.

I just got mine! It's a fully maxed out retina iMac (just 16 gigs of RAM though). Here's the benchmark:

I'm heading back to work but glad to answer any questions. The display is simply breathtaking and it seems fast as hell so far.

Admittedly, after all the buzzkill surrounding the Mac Mini, it's nice having some good news around here.

There shouldn't even be a quad-core Mac Pro. The $3,000 base model should be a 6-core.

Graphics and real world performance tests needed.

Who cares how fast processors are these days.
With all that screen res, all the time, I think the graphics performance and real world rendering and photoshop tests are more key.

What's funny is that a quad haswell mini would beat the lew end mac pro in cpu

There is a bit more to a Mac Pro now-adays than the CPU... Namely, dual high-end GPUs and high end PCI-e flash drives. I'd imagine those benchmarks still have the Mac Pro quite ahead of the game.

Please give us some benchm for the GPU 295x

The good news is they'll have to update the MacPro now, or look like idiots.


not necessarily.

The problem with the Mac Pro is that it is based on Server class CPU's. which have generally been a generation behind their consumer oriented brethren.

The new iMac's are using the latest, and fastest CPU's Intel has ever released.

the Mac Pro's are based on the latest Xeon Server CPU's which aren't generally the fastest. There is nothing Apple can do for the Mac Pro until Intel releases their next Xeons or, re-engineers the Mac pro again to use Consumer level components (Haswell I5's)

Being that the Mac pro's are using Xeon CPU's for their ability to run hotter, for longer periods of time, theirs not really the Apples to Apples comparison between CPU's since the usage scenarios are different.

I thought the high end iMac always hovered around the low end mac pros in terms of performance?


it is nothing new .. top spec iMac always outperforms the base quad mac pro
