Ryzen 7 5800 non-X reviewed

CAT-THE-FIFTH · 1 Aug 2021 at 09:51

It looks like an ideal upgrade from my Ryzen 7 3700X in my SFF PC:

Lower power consumption and greater overall performance!!

Its non retail so maybe some issues in getting one

It's just a low binned 5800x. You can get one by buying a 5800x and down-clocking it.
The Ryzen chips tend to be pushed very close to their maximum power usage out of the box, so pulling them back a little shows that they're actually all power efficient chips.

Not really, the 5800 is only 65W compared to the 110W of the 5800X..

Sure, it's got a 400Mhz lower base clock, but boosts up to within 100Mhz of the 5800X.

If you ask me, it's a much better chip than the 5800X!

It could also be a fair bit cheaper depending on availability.

Well it could be cheaper but tbh GN could have (and maybe should have) ran the 5800X at 65W to see if there was any difference in the efficiencies!

Indirectly they determined that 5800 nonX was worse silicon, didn't overclock as well.
From this I would say that 5800X in 65W ECO mode will be either same or better (and definitely better with curve optimizer applied).

That certainly shows that their sample is worse for overclocking, however without trying to also underclock / set the lower power limit on their 5800X can we actually say whether the 5800 or the 5800X performs better in 65W ECO mode.
Didn't the GPU-Z ASIC quality thing try to show some of possibilities:

It's the third line which makes it complex than just better overclock is better power consumption at lower clocks.

The critical factor would be the price and what an overclocked Cezanne chip offers.

The silicon's "type" or "design" is the same, the difference lies in the binning and drivers/bios (not all chips are exactly the same, so binning is the process of testing all chips of the same type and ranking them by speed). TDP is a made up number that represents the amount of heat a chip produces. By running it slower via down-clocking it consumes less power and produces less heat. Down/under clocking is a common trick used by anyone who wants to pull less power - the opposite to overclocking. It's an objectively worse CPU than the 5800x as an under-clocked 5800x would likely preform very slightly better for the same power consumption - or around the same, but would still be able to be clocked back up to it's box performance.

The only reason you should buy it over the 5800x is if:

It's cheaper
You can't work out how to under clock a 5800x.

does the "x" version of this cpu really get extra hot as I have seen in a couple of places on the internet and would a Noctua NH-D14 cope with it

Yes it does, 80+ in cinebench, casually spiking to 60+ during basic browsing.
Not an actual cause for concern, but can cause annoying fan speed ramp up. Might need to adjust fan curve.
D14 is plenty for it.

They are worse binned 5800X's. The stated boost clock may be within 100Mhz, but if you look at the all core frequencies, they're sitting at ~4.0Ghz to maintain the 65W TDP. You will achieve similar or better results enabling eco mode on a 5800X.

A bunch of these will eventually end on auction sites or AliX much like the Ryzen 1600AF did. A 5800X can be bought for around £350 so I think a chip like this with worse silicon and boost clocks should be around £50 cheaper. If I were in the market for an 8 core chips I would certainly get this over a crippled 5700g.

Yes this is a much better chip unless you need the onboard graphics

Not a given if you're buying used or grey market, which is the only to get one at the moment.

Why are all the interesting cpus oem :mad:

Hasnath · 3 Aug 2021 at 00:05

I'd love one to upgrade my unraid server.

Nice upgrade from a 3600...

The 5700G will perform well and if you need outboard graphics and low power use it’s a better option. The only real drawback with the 5700G is you don’t the pool of cache you do with the 5800X. And of course it can also double as a graphics card, so add a million pounds to the price.

The 5700G is probably the best true* desktop chip for desktop workloads and builds.
