AMD’s Ryzen 5 quad core CPUs are still a couple of months away, luckily however you won’t have to wait any longer to see how they perform. Benchmarks for quad core Ryzen CPUs vs Intel’s Kaby Lake i7 7700K speed demon are already here and they are very impressive.
Ryzen 5 quad cores haven’t been released yet, so how exactly can anyone claim to have tested a quad core Ryzen? Well, thanks to some very clever and flexible BIOS options introduced by AM4 motherboard makers cores, threads as well as L3 cache domains can be toggled on/off on AMD’s 8 core Ryzen 7 processors. By disabling cores/threads as well as half the L3 cache we can effectively create a quad-core Ryzen 5 CPU. That’s exactly what the folks over at zolkorn have done and that’s how we plan to bring you Ryzen 5 1600X benchmarks very soon. So, without any further delay let’s dig into the data!
The starting point is a Ryzen 7 1800X. Four of its cores and eight of its threads have been disabled. Also half of its 16MB L3 cache has been disabled to exactly replicate the L3 cache size that a Ryzen 5 quad core CPU would have.
In terms of clock speeds both the Ryzen 7 1800X and the Core i7 7700K have been set to a fixed 4.0GHz frequency. This represents a 200MHz overclock compared to the 1800X’s standard 4 core boost clock speed and a 200Mhz undernclock compared to the i7 7700K’s base clock speed. This effectively makes it a core for core, clock for clock comparison, IPC head-to-head of you will.
Quad Core Ryzen vs Intel Core i7 7700K – Gaming Performance
Amazingly the Ryzen quad core managed to outpace the 7700K in a few notable cases. Including the multi-threaded Cinebench R15 test as well as 3DMark Fire Strike and Fire Strike Ultra physics tests. In terms of gaming performance, the biggest lead the 7700K was in Far Cry Primal and it only amounted to approximately 10%.
That’s very impressive considering that AMD has already announced that it’ll be introducing the Ryzen 5 1500X quad core at around $200. If we look at stock vs stock performance by factoring in the 7700K’s clock speed advantage the numbers would translate to ~85% of the 7700K’s performance at ~60% of the cost. Which makes this an extremely attractive performance per Dollar proposition and that’s without factoring in the savings associated with AM4 X370 motherboards being less expensive than their Z270 counterparts.
