Core i7-7800X vs. 7700K, 6 or 4 Cores for Gaming?

Though we think about AMD’s Ryzen 5 1600 to be the candy spot for people constructing a brand new high-end gaming rig, lots of you curious about going Intel have been questioning whether or not it makes extra sense to purchase the Core i7-7700Okay or the brand new 7800X?

We presume the rationale why so many are asking this query is that the Core i7-7800X prices simply ~$70 extra and with that you simply get two further cores, but additionally entry to Intel’s newest desktop platform. There are different value issues to make, however we’ll talk about these later.

Earlier than we leap straight to the comparability benchmarks, let’s have a fast have a look at what the 2 Intel CPUs have to supply on paper.

  Intel Core i7-7800X Intel Core i7-7700Okay
Cores / Threads 6 / 12 4 / eight
Base Frequency three.5 GHz 4.2 GHz
Enhance Frequency GHz 4.5 GHz
TurboMax Frequency GHz 4.5 GHz
L2 Cache 6 MB 1 MB
L3 Cache eight.25 MB eight MB
PCIe Lanes 28 16
Reminiscence Configuration Quad-Channel Twin-Channel

The 7700Okay has a transparent clock pace benefit out of the field, although I may also be overclocking each CPUs for full testing functions.

Moreover the apparent core depend, maybe the largest distinction between these fashions is their cache design. The 7800X has 6x extra L2 cache however about the identical quantity of L3 cache. In fact, the 7800X additionally packs 50% extra cores and with that the TDP has been elevated by a bit over 50%.

We’ve got examined 30 video games, all of which have been performed on the GeForce GTX 1080 Ti. The 7800X was configured with 32GB of DDR4-3200 in quad-channel whereas the 7700Okay was armed with 16GB of dual-channel reminiscence. We examined each processors at inventory settings in addition to overclocked — the 7700Okay was set at a comparatively straightforward to realize 4.9GHz, whereas the 7800X was at 4.7GHz.

On with the outcomes…

First up we’ve got World of Tanks, not a very demanding sport however I am just about throwing the whole lot we usually check with at these CPUs. Right here we see out of the field the 7700Okay is 9% sooner than the 7800X — not an enormous margin, although it was shocking to search out that when overclocked the 6-core CPU nonetheless could not match the 7700Okay. This is not a CPU intensive sport anyway and since we’re pushing over 100fps always, the margins are considerably irrelevant.

Grand Theft Auto V is commonly used for testing CPU efficiency and right here we discover some sudden outcomes. Evaluating the minimal consequence we see that the 7700Okay is a large 30% sooner than the 7800X, overclocking decreased that margin to 18% however nonetheless, given there’s only a 4% distinction in clock pace as soon as overclocked it is a large win for the quad-core CPU.

Once more even overclocked the 7800X continues to be slower than the inventory 7700Okay, 10% slower in actual fact when evaluating the minimal body fee.

Since it is a widespread title proper now I assumed why not throw it into the combination. Should you’re taking part in with a dual-core or a lower-end quad-core and issues aren’t going properly do not hassle spending huge by investing within the 7800X. You may see virtually 30% extra efficiency when utilizing the 7700Okay in accordance with my testing.

The Witcher three is commonly talked about as being a CPU intensive sport and to a level it’s. That stated the 7700Okay is greater than able to getting essentially the most out of the 1080 Ti on this title and right here we see a lot the identical efficiency throughout the board.
