AMD Ryzen 7 5800X3D

[Shatun_Bear]

Do i need to repeat myself? The user I was replying to has a 2700x. You think he is rocking an x570 or an x570s?

I dont know what you are talking about, z170 support kaby, z370 supported coffeelake refresh, z490 supported rocketlake. What track record are you talking about

Ps1. I have a b550 aorus master and a 3700x

Jeez, I left this review forum for several days and I return to still see you on your Intel defence crusade

Nabbed one. Expected delivery tomorrow.

Nabbed one. Expected delivery tomorrow.

Same price in Poland after conversion. Granted it's sold by x-kom which likes to hike the prices.

Nabbed one. Expected delivery tomorrow.

Also got one

Leaving to pick mine up now

There seems to be plenty online in the USA with just NE and AMD so far (presumably soon B&H and Amazon and BB too). RIP to the scalpers on eBay asking $650-850.

When will they drop on Amazon?

410£ the 5800X3D
495£ the 5950X
360£ the 5900X

it’s still too difficult to decide…

if you have money to burn 5800X3D if not sit on your current and wait till next gen.

Beats me, but I would check at 8AM and 9AM Pacific, etc.

410£ the 5800X3D
495£ the 5950X
360£ the 5900X

it’s still too difficult to decide…

5950X, 5700X -> the sane choices imho, either all the threads/perf, or 65w is my reasoning
5900X -> if the 5950X costs too much but you really do need more than 16 threads
5800X3D -> if it really hits your specific use case, or you're a cpu hobbyist person

 

[Chomiq]

€519 in mindfactory

€586 at amazon.de, nuts!

 

[xorbe]

Weird, it's after 9AM Pacific and never showed at Amazon / B&H / BB. And out of stock at NE and AMD now. One of the eBay listings sold ...

When will they drop on Amazon?

Edit: Your time has come, it's on Amazon. (B&H is closed until Sunday for Passover.)

Price bumped up by €20 within a day at x-kom in Poland:

Yes they are the first to offer a commercial CPU with such a big L3 cache as you also say, ,, L4 off die isn't L3 on top of die

I agree, but honestly, this processor perfects what the Core i7-5775C attempted to do seven years ago. If you look at it, the reasoning is sound. I owned one for a while and it was a pretty great CPU, shame my Z97 board died and they cost more than that platform is worth it, so I flipped the chip. If you look at what it is, a low-power, low-TDP quad-core with a small L3, doing what it does... funnily enough Ian made a test for Anandtech back in 2020 which covered many games still in the bench suite today, and these are the same games that show exceptional performance on the 5800X3D today. Was it worth it back then? I would argue no... is it worth it today? I think it still isn't, for the price being asked. But it is the way forward, and once the packaging technology advances enough we should see this deployed throughout a full stack, on both companies' offerings.

I do appreciate your points on the similarity of it's L4 cache with this L3 vertical extension.
And agree with most.
I just think calling this, vertically stacked L3 a re hash of a 2.5D equivalent is beyond ridiculous.
It's a first for consumers, though I certainly agree a wider range (and Oc or at least PBO) would have been better than one SKU, for consumers.

Interesting chip to mention though while arguing against people upgrading to this, since identically Intel didn't spread their cache love far either, perhaps an expensive endeavour.

Ps5 and xbox need this 3d v-cache.. amd needs this on laptops and igpus for bandwidth

Thanks for sharing! The two most relevant graphs for each game IMO are Frame Time Variance and Average CPU Watts by FPS @ 1080p. In both cases lower values are better. The lower the variance, the smoother the overall gameplay. As for the other metric - lower power consumption for the same fps means better efficiency.

 

[The King]

Those not running a higher end GPU like the RTX 3080 in the review can expect much lower gaming improvements from running the 5800X3D @1080p

Maybe @W1zzard should also test with multiple GPUs or do a GPU scaling review with the 5800X3D

Ps5 and xbox need this 3d v-cache.. amd needs this on laptops and igpus for bandwidth

The Xbox One had an eSRAM cache sized around 32 MB. It is still present on the Xbox One S, was removed on the Xbox One X, and the PlayStation 4 never had it. Neither of the current generation consoles (XSS, XSX and PS5) have a high-speed buffer cache and this is unlikely to return to consoles any time soon. Regarding APUs, I believe it was considered and then disregarded because the cost of the processor would be fairly high for the market segment that these chips are intended to service, creating a niche that would not be worth it for AMD.

No doubt about it, the packaging technology is far more advanced and also this is more efficient because it is a level 3 cache and completely transparent not only to the OS, but to the processor internally, so anything that could even remotely benefit from data being closer to the processor cores in any manner will see a benefit with the X3D. It's a shame AMD decided not to refresh the Ryzen 9 lineup, I would sell my 5950X and buy a 5950X3D without thinking twice, but the 5800X3D is just not worth it for me.

EPYC 7373-X

EPYC 7373-X

Yes... kind of like a 7373X but for AM4. And for about 4 thousand dollars less, given that chip sells for $4600.

And with 2x CCD instead of 8? 105W instead of 240W? Seriously though, it would "only" have the same 96MB of L3 cache as it has to be duplicated across chiplets. Or, using the trick they used for the 7373X, you could take 4x CCD and disable half of the cores each - which I doubt they could do within the constraints of AM4. I really couldn't see them selling a 96MB version for less than $1k and a 192MB version for less than $1300. Would kind of take the shine off of them, value-wise.

I mean, the 5950X has two fully enabled "5800X dies" (but with low leakage), the 5950X3D simply needs to have two "5800X3D dies" in it (again, lower leakage versions). For its intended usage, that is really all it needs to do to achieve the same goal, eh? It's a desktop processor. The 3D cache layer is a 64 MB addition, the 5800X3D has 96 MB (32 + 64 3D slice), so a 5950X3D would have 192 MB (32 + 64 3D slice * 2), with 96MB L3/CCX/D.

Correct me if I am wrong, but I thought L3 across 2 chiplets had to be duplicated for core cohesion, meaning you cannot simply add up L3?
