iMac 2020 specs have been posted on Geekbench, revealing that Apple's next all-in-one computer will have reasonably powerful specs.

The leaked benchmark (for a rather uninteresting OpenCL test), discovered by sibling site Tom's Hardware, shows an unnamed Intel Core i9-10910 CPU with an AMD Radeon Pro 5300 graphics card. It shows the details of the iMac. This processor is capable of handling tasks with 10 cores and 20 threads, making it a solid desktop machine for creative professionals.

Geekbench lists the CPU as a Core i9-10910; Tom's Hardware speculates that this is a customized top-of-the-line processor from Intel's Comet Lake-S family, with a base clock of 3.6 GHz and a top clock of 4.7 GHz, and we suspect it will run at 3.6 GHz base clock and 4.7 GHz maximum clock. In other words, it runs about 29% faster than the standard Core i9-10900.

Tom's Hardware notes that the chip could be a 95W processor, placing it between the low-power 65W Comet Lake-S and the gutsy 125W CPU. Such a custom chip would be Apple's attempt to create a CPU that is energy efficient when needed and can increase power when needed to deliver high performance in bursts.

It is interesting to note that the iMac 2020 may feature an Intel custom CPU, given Apple's move toward producing its own ARM-based chips for the Mac and eventually moving away from reliance on Intel processors.

As for graphics, the Radeon Pro 5300 appears to be a desktop version of the Radeon Pro 5300M designed for laptops; Tom's Hardware reports that the iMac's Radeon Pro 5300 is based on the latest Navi 14 GPU and emphasizes that it should have 1,280 stream processors.

The Geekbench listing stated that the graphics card was clocked at 1,600 Mhz and had 4 GB of onboard memory. It is worth noting, however, that the Radeon Pro GPUs are designed for professional graphics tasks such as CAD tasks and video rendering, rather than high-end gaming.

All of this means that the iMac 2020, which will feature a new design and is expected to be unveiled in late 2020, could be a significant upgrade over its predecessor. the Geekbench listings include single-core and multi-core CPU test results are not listed, but we expect the latest Intel processors with 10 cores to deliver strong performance.

We look forward to seeing what Apple will create with the upcoming iMac, especially given the Mac Pro 2019's radical look. However, we'll have to wait at least a few months before Cupertino's staff pulls the covers off the iMac 2020.
