[News] Simulated AMD Ryzen 5 Series Chips as Fast as Ryzen 7 at Gaming

It's not rocket science to simulate smaller upcoming Ryzen series chips when you have a Ryzen 7 1800X. By disabling two out of its eight cores and adjusting its clock speeds, TechSpot simulated a Ryzen 5 1600X processor. While the Ryzen 5 1600X was a near-perfect simulation by TechSpot, the 1500X isn't entirely accurate. AMD is carving out the 1500X by disabling an entire CCX (quad-core complex), leaving the chip with just 8 MB of L3 cache, disabling four cores on the 1800X still leaves the full 16 MB L3 cache untouched. The Ryzen Master software lets you disable 2, 4, or 6 cores, but not specific cores, so it's entirely possible that disabling 4 cores using Ryzen Master turns off two cores per CCX. Nevertheless, the gaming performance results are highly encouraging.

According to the gaming performance figures for the simulated 1600X six-core and 1500X quad-core Ryzen chips put out by TechSpot, the 1600X barely loses any performance to the 1800X. Today's AAA PC games have little utility with 8 cores and 16 threads, and you'll hardly miss the two disabled cores when gaming on a 1600X powered machine. The simulated 1500X loses a bit more performance, but nothing of the kind between the quad-core Intel Core i7-7700K and the dual-core i3-7350K. When paired with a GeForce GTX 1080 Ti in "Mafia III," for example, you lose 12.8% performance as you move from the $499 1800X to the $189 1500X (simulated); but you lose 35% performance as you move from the $329 i7-7700K to the $189 i3-7350K.

I'm not sure this is really news. Most people have known for a while there's not much benefit to more than 8 threads in gaming.

Especially when you consider the R5 series is a cutdown R7 with the full L3 cache, this shouldn't come as a surprise to anyone.

Well, it should be common sense knowledge, but on some forums still there are claims that 4 cores are different chips , hopes of much better overclocking, and single CCX build that may be faster in gaming.

lol that's been discussed to death already. If some still believe that, they are primed for disappointment.
