AMD has officially launched its high performance Ryzen Threadripper processors. With up to 16 cores and 32 threads, Threadripper delivers an impressive performance per dollar value, giving Intel’s high-end desktop products something to worry about.
Recently, AMD shared a new piece of information regarding these CPUs and how it makes sure they run as cool as possible, with the least power draw.
AMD Ryzen Threadripper built using their Best Zen Dies
According to AMD, the pair of Zen “Summit Ridge” dies that make up the Ryzen Threadripper multi-chip are heavily binned. In fact, only top-5% of the silicon chips are selected to manufacture the Threadripper processors.
The usage of the highest grade Zen dies is to keep electrical leakage to the minimum. This ensures that Threadripper is as power and thermally efficient as possible.
As a result of this, Threadripper chips will overclock better than their Ryzen 7 counterparts. Reviews show that the flagship Ryzen Threadripper 1950X can hit 4.0GHz on all cores, though the required voltage should also increase.
Ryzen Threadripper: CCX Configuration and Infinity Fabric
The AMD Zen core used in Ryzen is composed of two 4-core/8-thread CCX Core Complex modules which are linked to form an 8-core/16-thread die. In other words, you take two Zen dies, place them on a TR4 socket and you have a new Threadripper CPU.
Based on the same logic, the Threadripper 1950X has two 8-core chips, the 1920X has two 6-core chips and 1900X will use two 4-core chips. At the CCX level, this is represented as 4+4+4+4, 3+3+3+3 and 2+2+2+2 cores respectively.
AMD uses an interconnect called Infinity Fabric to link together parts of the chips with massive bandwidth. On paper, Infinity Fabric is not as fast as Intel’s monolithic design, but it’s easy to assemble and scales better.
The design helps AMD cut expense of manufacturing to such an extent that it is offering a 16-core, 32-thread CPU for the same price as Intel’s Core i9 with ten cores and 20 threads.
Ryzen Threadripper Specs and Pricing Detailed
So far, AMD has released two Ryzen Threadripper SKUs with more arriving in the coming months. Below are the specification and pricing details of both these CPUs which are now available for purchase.
The Threadripper 1950X is the flagship chip featuring 16 cores and 32 threads. The chip runs at 3.4GHz base and 4.0GHz boost clocks, with the XFR mode allowing for an additional 200MHz. It is priced at US$999.
The second chip in the Threadripper lineup is the 1920X which features 12 cores and 24 threads. The chip is clocked at 3.5GHz base, 4.0GHz boost and the same XFR headroom as the 1950X. The Threadripper 1920X costs $799, which is $400 less than Intel’s 12-core rival.
The Threadripper 1900X is an 8-core, 16-thread chip and is scheduled to hit the market on August 31. The chip is clocked at 3.8GHz base and 4.0GHz boost. When compared with AMD Ryzen 7 1800X, the 1900X not only runs at higher clock speeds, but it also offers more PCIe lanes and more I/O support. The chips will cost $549.
The Ryzen Threadripper chips feature a whopping 64 PCIe 3.0 lanes and quad-channel DDR4 memory clocked at 2,666MHz. They are all multiplier unlocked, with a TDP rating of 180W. The chips are compatible with AMD’s new X399 PCH based motherboards.
