Labs with Apple's new Core i9 iMac 5K with Vega graphics: landmarks and first impressions



[ad_1]

Now that we have a new range of iMacs, we have upgraded the iMac 5K 27-inch with the Intel i9 8-core processor and the Radeon Pro Vega 48 graphics card for optimal performance. Our first impressions with this new machine are very promising. So what are the benchmarks?

Apple refreshed the new iMac lineup just days before its "Apple News +" service-centric event on March 25th. Although this event did sink a lot of ink, desktop users were delighted to find that the specifications of the iMac were so necessary.

We've already explored the basic 4K model and found that the upgrades were good enough for the low-end model. This did not stop us from splurging on the 27-inch much more powerful.

Specifications and design

We also took the largest 5K iMac with the Intel 8-core 3.6GHz i9 processor, Radeon Pro Vega 48 graphics cards and 16GB of RAM.

All of this is internal because the exterior is largely unchanged from what we have seen before. The design always looks beautiful, but with large glasses and a large "chin", it seems to have enough time for a refresh and catches some heat for not having a new look. We understand – it seems a little dated at this point, after its launch four years ago in 2015.

Also on this machine is a 2 TB Fusion Drive and 2 GB of VRAM.

This machine paid us $ 3349.00 before taxes – but at the time of publication, it may be on sale for $ 3,149 with the coupon code. APINSIDER.

Marks

For starters, we used Geekbench 4. Our machine got a single-threaded score of 6313 and a multi-core score of 32954. These are pretty solid numbers, especially compared to the iMac Pro base. This model beats the basic iMac Pro in single-core and barely loses the multicore test. This increase in performance is due to more cores and higher frequencies than any change in the actual architecture of the chip compared to previous years.

The landmarks are controversial. They are never a direct correlation to the workflow of an individual. And, they change continuously as the power of the computer increases and paradigms change. More specifically, a AppleInsider In resistance test, Cinebench now has an R20 version, totally incompatible with the results of the R15 version.

The new R20 version has increased the complexity of the workload, increased memory usage and adopted the latest Cinema 4D R20 rendering engine, which will ultimately give us much better and accurate results. We will use that in the future, rather than the R15.

Our 5K iMac 2019 got 4108 on the Cinebench R20. More importantly, by monitoring the processor with the Intel Power Gadget, we did not see any indication of thermal limitation below the rated speed of the machine. It never went below the advertised frequency, even after performing back-to-back testing and increased heat.

Following this, we launched Unigine Heaven Benchmark 4.0, which is primarily a game reference, but remains a good indicator of graphics performance. We kept the default settings and ran the test multiple times. We gained average SPFs of about 68 FPS and a maximum of 125.3. These Vega graphics are really profitable.

As we mentioned, this unit has the Fusion Drive 2TB. This is a good mix of capacity and performance, with average write speeds of 725 MB / s and read speeds of 2490 MB / s in the BlackMagic drive speed test. To further increase these numbers, you can opt for a smaller internal SSD and use an external Thunderbolt 3 storage to increase capacity. That's probably what we would do if we built this machine again.

We will continue to test this machine and will soon have a full review. So stay on the lookout for new covers of the new iMac 2019 lineup.

Until now, this machine has impressed us, especially with regard to the comparison with the iMac Pro. If you find yourself on the new market and you do not need the possibility of changing the processor of the iMac Pro that voids the warranty, it 's all about. a powerful machine that allows you to achieve the same performance at a much lower cost.
