Also 10% back if you use your Amazon prime CC. Still undecided between this or the 5800x 3D myself.

FWIW it really depends on your GPU how much difference the CPU will make..


You're always going to be CPU or GPU bound... at higher resolutions you're more likely to be GPU bound with most GPUs--- so differences between CPUs will appear much smaller.

Here's a story on CPU scaling back then the 3000 series was kind, where if you were running something in 4k max you'd see just a few FPS difference between literally any modern CPU made in the previous 5 or so years.... i3, i5, i7, R5, R9, all meh.

The i9 is barely more than 3% ahead of the i3. The R9 is almost identical to the R5 at 4k.

Hell the nearly decade old now i7-4770k was only a bit over 8% slower than the leader at 4k.

Because the GPU was the bottleneck.


Now drop down to 1440p max and differences get a little bigger... i3 to i9 is now a jump of over 10%... and that poor 4770k is over 25% behind the leader... because some CPU bottleneck is leaking through.

At 1080p the gap is larger still, over 20% between i3 and i9 and almost 50% difference from that 4770k to the leader as your bottleneck is largely in the CPU now not the GPU...




Now, if you're running like a 3060ti or something, you're gonna be GPU bound a lot sooner, meaning the "CPU makes little difference" threshold will drop a fair bit.


In contrast, the 4090 finally gets us to a world where you can be CPU bound even at 4k/Ultra... (which is the only reason I finally moved from my 3600x to a 5800X3D when I upgraded from a 3090 to a 4090, since all my gaming is at 4k)

That for example is 53 games benchmarked on a 5800x vs a 5800x3d with a 4090 in both.

Even at 4k you see a near 7% difference on average, and double-digit differences (some in the 20-30% range) in almost a third of the games favoring the 5800x3d... certainly there's many games there still GPU bound, but a shocking # that aren't.


At 1440p with the 4090 the 5800x3d is over 15% ahead of the 5800X on average, and more in the 20-35% range in almost half of em.
