AMD's TR 1950X (16 cores) and TR 1920X (12 cores) CPUs will be released on August 10th:

The news at the top of the hour is the date at which AMD is making Threadripper and associated TR4 based motherboards available at retail: August 10th. This is expected to be a full worldwide retail launch, so don't be surprised if your favorite retailer starts posting teaser images about how much stock they have. August 10th will see both the 1950X and 1920X with their retail packaging, along with motherboards from the main four motherboard vendors.

AMD has also announced an 8-core version of Threadripper, the TR 1900X, for $549. Why buy it instead of spending $300 on the Ryzen 7 1700 or $420 on the Ryzen 7 1800X, both of which have eight cores?

There are some questions around why AMD would release an 8-core Threadripper, given that the Ryzen 7 1800X is also eight core and currently retails around $399 when distributor sales are factored in. The main thing here is going to be IO, specifically that the user is going to get access to quad channel memory and all the PCIe lanes required for multi-GPU or multi-add-in cards, along with a super high-end motherboard that likely contains multiple CPU-based PCIe x4 storage and/or 10G Ethernet and additional features.

    Memory remains a severe bottleneck - until/unless it's on-cpu-chip in significant amounts, the distance between the CPU and the memory will eat that speed like a pothead with a fresh bag of Fritos.

    High Bandwidth Memory [wikipedia.org] (or the similar Hybrid Memory Cube [wikipedia.org]) and subsequent versions have helped massively on that front.

    Post-NAND replacements like Crossbar RRAM, PCM, or memristors were supposed to enable terabytes of memory with similar endurance and speed to DRAM. Instead we have gotten 3D XPoint. Maybe in 10 years that situation will change.

      There's some hope there, all right. But a lot of the bandwidth comes from wide access; that's not going to help at nearly as much when access is a word here and a word there. Until we get optical or some other inherently high-speed storage that works and is affordable, likely memory will remain slower than processors and cache will remain the word of the day.
