why are amd processors so much slower than intel in games

[dave_the_nerd]

I agree that it isn't really that big of a deal in the Ryzen generation (It was in the Dozer generation).

But don't correct one inaccuracy by stating another. Intel works just fine with multi-threaded games.

What games run faster on Ryzen than Coffee Lake?

Civilization apparently. *shrug*

I was thinking of the 7xxx series when I wrote that though. Yes, hex-cores are basically "enough" cores for gaming, and it comes back to individual core performance, for the most part. (Memory, Storage, and GPU notwithstanding.)

I assumed OP was talking about Ryzen. You can see the inter-CCX penalty lowering the draw call perf in the benchmark.

For Excavator and older AMD architectures, they're just really bad at draw calls. Couple that with lower raw processing power than their competition, and you get poor game perf.

OP didn't say. AMD has had a reputation for being slow in games for over a decade.

Over the time period between Conroe's release and now, the majority of AMD designs have suffered from a combination of low clockspeeds (exception: some BD derivitives), lower IPC in general, and weaker cache/memory performance.

CCX penalties are a recent phenomenon, and there are some things that end users can do to mitigate those problems. It will be interesting to see how Ryzen 2 and 3 fare in the future.

Unfortunately, even with very fast DDR4, the inter-CCX penalty is still very prominent. When the driver and game threads are running on a single CCX, even with 2133Mhz RAM, the draw call perf will be higher than if it was on two CCXs and running the fastest DDR4 on the market.

Ryzen 3 may have a different DRAM/IF ratio though. Wait and see.

Depends where you look:

Something is a little off somewhere. At Anand even the R5-1600 beats the 8700 in Civ6. While at Toms the 8700 beats even the R7 1800X.

The way this thread title is worded is way too ambiguous and misleading. OP provides no specifics as to which AMD and Intel processor's he's referring to or what games are slower.

I don't want this to simply be an AMD vs. Intel flame thread so it's locked.
