The rightfully “more expensive” Ryzen 9 5950X justifies itself with 63 percent more performance. With Intel stuck in the mud at 14nm, the best it can field in a smaller consumer socket is 10 cores in the Core i9-10900K. There, it’s the total knockout you expected. Technically, the XT was the best of the best of Zen 2, so when you compare the Ryzen 9 5900X against the Ryzen 9 3900X it’s actually a 20.7-percent increase in performance in an all-core load.īut no one really cares about red-on-red performance-nerds only want to see red-on-blue.
One step down, the 12-core Ryzen 9 5900X is less power-restrained, and we see it open up an even more impressive 17-percent gap over the 12-core Ryzen 3900XT. The small-socket AM4 can’t push the same power like a big-socket Threadripper TRX40 socket. While 14 percent is an incredible bump, AMD said much of the limitation on all-core loads is due to the CPU socket power limit. On top is the new Ryzen 9 5950X with 16 cores, which offers an impressive 14-percent increase in performance over the 16-core Ryzen 9 3950X chip. With the unified 8-core CCX, the latency is essentially eliminated. AMD said it has measured this latency in a range from 78ns to 95ns. This design lead to a latency cost when the cores had to communicate outside of the 4-core CCX. With previous Ryzen chips, each CCX was constructed of four x86 cores, which were connected to a second CCX to make a core chiplet die (CCD). This let AMD get its newest cores into existing sockets and motherboards without disturbing everything underneath it. Zen 3, for example, uses the same IO die that contains the PCIe 4.0 lanes and memory controller as Zen 2. Unlike Intel which fashions its CPUs from a monolithic piece of silicon, AMD assembles Ryzen from multiple “chiplets.” This gives AMD far more flexibility in yields and construction. Latency, however, received one of the biggest upgrades, with a redesign of the core complex (CCX), the basic building block of the chip.
The first red entry, AMD’s original Ryzen processor, would upend it all by offering an 8-core CPU for less than half of what Intel had been charging the year before.įor the cores themselves, AMD improved integer performance, floating point performance, and branch prediction. At the top you can see the calm, blue waters of Intel, whose only competition was itself, testing the limits of just how much it could charge a consumer for a CPU (Hint: it was $1,723). You can see just how disruptive Ryzen has been by looking at the table below, which summarizes the last five years of consumer desktop computing history.

There’s a lot to unpack with these new CPUs, but we understand if you want to skip to “the good stuff.” So read on if you want to hear about AMD’s path to glory over the past few years, or feel free to jump ahead to these upcoming sections:
