Apple M2 Ultra
Apple (MacRumors, Hacker News, Slashdot):
M2 Ultra is built using a second-generation 5-nanometer process and uses Apple’s groundbreaking UltraFusion technology to connect the die of two M2 Max chips, doubling the performance. M2 Ultra consists of 134 billion transistors — 20 billion more than M1 Ultra. Its unified memory architecture supports up to a breakthrough 192GB of memory capacity, which is 50 percent more than M1 Ultra, and features 800GB/s of memory bandwidth — twice that of M2 Max. M2 Ultra features a more powerful CPU that’s 20 percent faster than M1 Ultra, a larger GPU that’s up to 30 percent faster, and a Neural Engine that’s up to 40 percent faster. It also features a media engine with twice the capabilities of M2 Max for blazing ProRes acceleration.

Update (2023-06-13): Hassan Mujtaba (via Hacker News):
The CPU managed to post a single-core score of up to 2809 points in single-core and 21,531 points in the multi-core tests. For comparison, the Intel Core i9-13900KS scores 3083 points while AMD’s Ryzen 9 7950X scores 2875 points. In multi-threaded benchmarks, the same chips score 21665 and 19342 points, respectively. So as you can see, the workstation-grade Apple M2 Ultra SoC isn’t faster than the mainstream CPU offerings from Intel and AMD.
[…]
If you compare the chip to something like an AMD Threadripper and Intel Xeon W chip, then those would absolutely crush the M2 Ultra in the multi-threaded tests but the single-threaded lead will be on Apple’s M2 Ultra[…]
[…]
As such, in OpenCL, the M2 Ultra SoC ends up 50% slower than NVIDIA’s RTX 4080 and that’s not even the flagship GPU.
As expected, these scores confirm that the M2 Ultra chip offers up to 20% faster CPU performance compared to the M1 Ultra chip, as Apple advertised.

Sadly, the front Thunderbolt ports aren't functional. Plugging an ACASIS Thunderbolt SSD enclosure to the front results in "USB Accessory Needs Power". Drives can only be used when plugged into the back.
