Another iMac Pro has recently appeared on, the third revelation in three months. First announced back in June, Apple suggested that they will come up with the most powerful iMac Pro this coming December.

Interestingly, a new and more powerful processor shows up each time a new iMac Pro benchmark result surfaces. One constant is the Mac OS X 64-bit, the presumed pre-installed operating system at launch.

Powerful iMac's

Apple has promised to develop a new iMac Pro before the year ends. As posted by the Cupertino-based company on their website, “The all-new iMac Pro, with its gorgeous 27-inch Retina 5K display, up to 18-core Xeon processors and up to 22 Teraflops of graphics computation, is the most powerful Mac ever made.”

The first model that surfaced on the benchmark website back in Aug.

22 is powered by Genuine Intel 8-core/16-thread (2.40GHz base frequency) processor. The processor was tested in both single- and multi-core performances (Geekbench 4.1.1 Tryout for Mac OS X x86, 64-bit), scoring 3817 and 23397, respectively. A 128GB 2666MHz DDR4 RAM was used during the benchmark.

The next model is powered by Intel Xeon W-2140B 8-core/16-threads (3.20GHz) processor. Tested using Open Computing Language (OpenCL), this iMac Pro was integrated with 32GB 2666MHz DDR4 RAM and AMD Radeon Pro Vega 56 Compute Engine. The result is an outstanding OpenCL score of 162154. The single- and multi-core scores are 3826 and 23676, respectively.

Intel Xeon-powered

And just recently, got the result for the iMac Pro model that is powered by Intel Xeon W-2150B 10-core/20-thread (3.0GHz) processor.

Like the first model that surfaced, it was tested for both single- and multi-core performances (Geekbench 4.1.0). The final tally – single-core score: 5345 and multi-core score: 35917. A 64GB 2666MHz DDR4 RAM was used during the test.

Notice the results between the first two Intel processors? The first Intel processor (non-Xeon) only has 2.40GHz compared to the second (Xeon) with 3.20GHz, and the proximity of their scores is very close.

While it was a processor test, one couldn’t help but notice the difference between their RAMs: 128GB vs. 32GB.

The future of iMac

Imagine how powerful Apple’s intended “most powerful iMac Pro ever” – an 18-core/36-thread CPU, 22 Teraflops of GPU Performance (up to 16GB HBM2), up to 4TB of SSD, and 128GB of ECC RAM. This monster computer also supports four Thunderbolt 3 ports, connections of up to two high-performance RAID arrays, and two 5K screen displays – all at the same time – plus a 10GB Ethernet connection.

Apple is expected to start shipping iMac Pro this coming December. As posted on Apple website, the starting price is at US$4,999.
