The Ryzen 5800 (non X) OEM has been 'stealth launched' for prebuilt PCs

I would've been really tempted to buy this if it was available to buy a few weeks ago. It's basically the same CPU as a 5800X, but which a much lower TDP and only a slight reduction in all core clock, so it doesn't need to be paired with a cooler rated for 220w TDP (so a Noctua NH-U14S or greater).

Apparently, they are putting it into uber expensive Alienware prebuilt systems.

I'm just wondering if these will be available to buy anywhere, or will they only ever be found in prebuilt systems? Would be well priced at £350 or less.

I think the 5800 OEM would definitely beat any 8 core currently offered by Intel, except for the ridiculous 11900K in a few benchmarks.

This would be a fantastic £349 chip, depend on AMD's supply, if their wafer supply improves greatly then maybe yeah, AMD are moving to 6nm for Warhol later this year which could free up 7nm for existing 7nm Zen 3 CPU's as a lower price bracket.
 
65w limits eh

That's going to hurt in sustained loads as those oem cpus retreat to the greatly reduced base clocks.

On the other hand it's alienware computers, who's going to work on those.
 
Apparently, it's possible to overclock these to speeds similar to the Ryzen 5800X at stock, so that would probably involve lifting the default power limits too.

I think the reason these haven't been sold as retail CPUs, is AMD can't / doesn't want to include a decent enough stock cooler to keep it under 80 degrees under load, at higher clock speeds. Inevitably, the Wraith Spire cooler (included with the Ryzen 5600X) would not cope with the higher core count (and power draw) of the 5800 OEM.

If sold with prebuilds, the CPU cooling is upto the company building it, they can afford to throw in a good cooler, or maybe not in some cases (beefy cooler won't fit in many systems) and just run it at a lower clock speed / power limit.

If the Ryzen 5600X couldn't be cooled with a stock cooler (this is debatable as the stock cooler can hit 90 degrees under load), it would've become a more premium product, with a lower clocked version being sold with a stock cooler.

Eh, there was a larger stock cooler but AMD abandoned the premium stock cooler angle in favour of zero cooler while simultaneously increasing prices :p

It's written in the contract that the moment you take the lead in cpus you have to become evil.

Taking a leaf out of Intel's book, if you provide a box cooler some reviewers will use it and if they don't provide the best performance it doesn't show them in the best light, especially given that Intel don't provide a box cooler and these reviewers then default to £100+ AIO's for them, even Hardware Unboxed did this.

The solution, don't provide a box cooler, lesson learned. I even said this at the time...

Probably what these are for - companies like Dell stick em in pre-builds, stick barrel scraping cooler on them, BIOS with limited turbo, etc. to keep thermals and power in check (so they can go cheap on the PSU and power delivery on the motherboard as well) but then market it as high end, comparable to 5800X, and price accordingly - even though you'd probably see 30% lower performance than something built around a 5800X.

I’m using the wraith spire on my 5800X and it maxes out at 81c stock in R23 10 minute run, got it down to 74c now I’ve configured ppt to 125 with -25 all core CO while scoring about 800 points higher than stock.

Only if you leave them on stock, my 3900 OC's to same levels as 3900x's rather happily, I can't see this being any different. The stock clocks are much lower yes but you can just set them manually to higher frequency.

Wow, thats good, I wonder if they can all perform this well?

Doesn't make sense that they don't include a cooler with it, if so (but can afford to with the significantly cheaper 5600X).

On a review I looked at, they used a beefier Noctua NH-U14S to cool a 5800X, which kept it at 75 celsius at stock. Link here:

I think the main heat transfer bottle neck for this CPU is between the IHS and the coolers baseplate and this is why some people even with powerful coolers report high temps as the spot right over the chiplet isn't making as good a contact as it could be due to some imperfections either with the baseplate or the IHS.

Also a lot of these coolers were designed with Intel chips in mind so the baseplate is slightly convex to ensure a die that's positioned right in the middle of a CPU gets the best contact but with with AMDs chiplet approach the die is offset to the side so contact with the die is not as good.
