AMD Reveals Ryzen 7 With 3-D Chiplet Technology
AMD also revealed a new Ryzen 7 CPU coming in the spring that it said will be the “world’s fastest gaming processor” thanks to its use of the chipmaker’s 3-D chiplet technology.
The new Ryzen 7 5800X3D desktop CPU will provide, on average, 15 percent faster performance for gaming compared with the Ryzen 9 5900X. This performance gain is made possible by a vertical cache that is stacked on top of the CPU, appropriately called the 3-D V-Cache, which gives the CPU a total L2 and L3 cache of 100 MB, much higher than the Ryzen 9 5900X’s 70 MB.
AMD said the 3-D V-Cache has a bigger impact on games that “have an incredible sensitivity to memory latency.” This includes “Watch Dogs: Legion,” which saw up to a 40 percent performance improvement when comparing the Ryzen 7 5800X3D to the Ryzen 9 5900X. The 3-D chip also saw up to a 20 percent improvement for “Far Cry 6,” ‘Gears 5” and “Final Fantasy XIV.”
On a competitive level, AMD is considering the Ryzen 7 5800X3D a victory against Intel, based on a handful of tests, only half of which showed AMD in the lead. The 3-D chip was 20 percent faster for “Final Fantasy XIV” and 10 percent faster for “Shadow of the Tomb Raider” and ‘Far Cry 6,” according to AMD. But it was a tie for “Watch Dogs: Legion,” “Gears 5” and “Counter-Strike: Global Offensive.”
In addition to its 100-MB cache, the Ryzen 7 5800X3D sports eight cores, 16 threads, a 4.5GHz boost frequency, a 3.4GHz base frequency and a 105-watt thermal design power. The processor is compatible with AMD 400 and 500 Series motherboards.
