CPU for RX 6900 XT - HELP/ ADVICE

[BenjaminSexyBoy]

Hey guys,

I'm getting a RX 6900 XT for a future build and am unsure what CPU to buy (1440p gaming).

I am currently split between 3 options:

 

Options:

1. i7-12700k - $579

2. Ryzen 5 5600x - $325

3. Ryzen 7 5800x -  $499

PRICING IN AUD

Planning on lightly overclocking

 

- budget isn't of much concern but would prefer something around this price range

- willing to shell out a bit more money if greatly beneficial

 

Workload: Gaming (Heavily modded Minecraft (fairly CPU intensive), and newer titles like Cyberpunk 2077 and Microsoft Flight Sim

 

Questions:

1. What the best pairing pairing for my circumstance?

2. are there disadvantages to using an intel CPU with an and GPU?

Feel obliged to suggest improvements

 

If you have any questions for me feel free to shoot me a reply 

 

Thanks,

Benjamin

The Ryzen 7 5800X3D cause it's one of the best gaming CPU-s.

Given those options, I'd go 12700K. It is the best single thread performance and in games (especially at 1440P) that is what matters. The 12600K would also be a good option, it's the same multi core performance as the 5800X but again, the single thread performance of the 12700K and a fair bit cheaper as well.

 

There is another option you can do, though it is a bit less practical. You could wait for the B660M Mortar MAX or the B660M PG Riptide to release in your area, they're LGA 1700 motherboards with DDR4 support that are relatively cheap and support BCLK overclocking on non-K CPUs like the 12400 and 12700. It would let you save some money and get a more fun to overclock system, though you will get weaker memory overclocking support and you might have to wait a bit for those boards to reach Australia. 

 

There shouldn't be any issues running a 6900XT on an Intel system. It's a great GPU and everything. One thing I'd suggest is that you make a Soft Powerplay table for that card to disable the power limits. That will (in my testing at least) get you an extra 10% performance uplift by doing that before even touching the core clock sliders.

You also have to consider the cost of a Z690 motherboard and DDR5 Ram. Even if you go for DDR4, that motherboard is at least double the cost of a good B550 motherboard that can drive both of those options. So although the 12700k is the best CPU in general, it'll raise the overall cost of the system because of the platform.

 

If you're ok with that though, then sure go for the 12700k. It has the best single threaded performance out of all of those, and the best multi threaded performance as well, for shorter workloads. Ryzen is still the best for tasks which need the CPU to run for hours upon hours.

 

But if all you do is gaming, then the 5600X or heck even the 12600k, which has much fewer cores than the 12700k, both work fine because you have almost zero need for those extra cores, even in extremely modded minecraft. Games just aren't built to utilize that many cores so unless you do extra stuff like streaming or 3d modelling or animation or video editing, you really don't need the extra cores. And the argument can be made for having stuff open in the background but even then, both the 5600x and 12600k are more than capable of that.

 

If you do want the system to last as long as possible though then you'll wanna go for the 5800x or the 12700k because games are starting to utilize more cores due to the PS5 and Series X.

 

Ultimately, no matter what option you choose, you will be satisfied with it. At these brackets they don't differ by good or great performance, but instead with really high and max performance. So even with the 5600x you'll be left a satisfied customer.

Personally i would go for the 5800x3D if you want to use your System for mainly gaming
you can see the LTT review here :

cause for a cheaper price and a cheaper motherboard you'll get similar performance in games with 12900KS (or as Linus says "Keep Spending" XD) which needs more expensive DDR5 and more expensive motherboards (not to mention the 800$ price tag of the CPU)

if you do other stuff besides gaming like video editing, the best choice in my opinion would be the 12600KF or 12700KF

Hey I concur with the other posters. I'd get the 3d if I were you. Sounds like a great combo with the 6900xt. Then again if the 5900x is on sale, it's not a bad choice for a system like yours, from the reviews I saw it isn't much slower than the 3d on gaming and it is somewhat faster on some programs, though I'm not sure you'll use them. You also get to save a bit on memory as someone said, as it uses ddr4. Look for a mobo from tier A or better. If you need to cut corners I'd get a decent but cheap case like the Fara R1 and cheap fans (I got Raijintek Iris 12 and am pretty happy with them, my daughter loves the little ARGB remote lol). You can always give the PC a makeover later on if you want a better case/fans.

You should either get a 12700kf or a 5800x3d if this is mainly for gaming if not then just get a 12600kf or 12700f
