AMD Ryzen 7 5800X3D

[AnotherReader]

This lives up to AMD's performance claims. I'm not surprised, but a few other of our fellow forum members might be pleasantly surprised.

So basically its about 3-4% faster in games than a 12700f, but gets absolutely creamed in everything else (single thread, multithread, upgradability) while also costing 50% more? Woah, thats just a bad product. Needs a big pricecut to 300-350. At 450 its a joke

 

[tussinman]

Er no, once it's given proper fast RAM and the BIOS/driver update it will be the fastest gaming chip on the planet at *half* the power of the toaster 12900K for 2/3 the price...

I think he's more referring to price against realisitic alternates, obviously that doesn't include the 12900k.

12700k for example is over 10% faster in CPU test, only 2-3% slower in gaming + has 13th gen support and it's $100-125 cheaper. 5700/5800X is only like 6-9% slower in gaming and can be had for 25-30% cheaper

Imagine having a new platform with a new PCIe bus, ram speed, new IPC, etc. AMD just sticks some more cache on top of the CPU while consuming considerably less power and tying your performance in games (if not better with the 1% lows). Just sold my Intel stock.

AMD Ryzen 7 7800X3D

"1.35v is the highest the vcache supports, therefore the maximum possible frequency is 4.5 GHz"

yeah that's cute, tell me more

Hopefully AM5 won't have these.. Funny features, let's call them that, yes.

This happens across the Zen 2 range (personally tested on a 5700G, 5800X and 2 x 5900X). It's called clock stretching, and only really useful if all you care about is seeing a bigger number in monitoring software.

If you run Cinebench R23/CPU-Z then you'll find you're nowhere near the 16k multi/1650 single or 7000 multi/650 single you should be at for those clocks.

I am still waiting for the MSI Changelog where it says that it has The AMD 3D V-Cache Performance Optimizer listed on their Beta Driver. Otherwise guys. Let's just wait for Benchmarks with Actual Released Bios.

thanks, appreciate the schedule, look forward to perhaps some more data with proper RAM...feels a little unfair to give Intel one of the fastest RAM kits on the market but limit Ryzen to 3600C16, no? Or given the ludicrous power numbers perhaps some FPS/watt?


Completely agree, this is a pretty major drawback of the review but can hopefully be fixed soon


hmm DDR5 kit ~$600 in UK vs ~$250 for DDR43600C16 -in fact you can get 32GB 4000Mhz+ DDR4 for ~$300

Patriot Viper Steel 16GB (2x8GB) DDR4 PC4-35200C19 4400MHz Dual Channel Kit (PVS416G440C9K) | OcUK (overclockers.co.uk)

IDK about UK but you can get a 6000 CL 36 kit here for $360 -- in fact that's what I'm running now, and it's faster than my old DDR4 32gb 4133 4x single rank b dies.

Prices aren't that different here anymore and haven't been for a while.

The gaming numbers look really good, but I'm underwhelmed by the synthetics and number crunching and server benchmarks. The performance of Milan-X over the non-cache variant is simply staggering, at least in Linux. Maybe it's because that's 768MB of cache as opposed to 96MB, but I was expecting it to at the very least, be on par with the non 3D variant with slightly higher clocks. It will be interesting to see if Phoronix does a review of this chip on Linux and to see if those results match the same kind of trends we're seeing here.

I just downloaded the Driver and there were no reference for a 5800X3D Optimizer Driver.

You downloaded a bios not a driver two different things.

@W1zzard Any chance you can run the matrix UE5 PC demo on it would love to see if the cache helps with that.

AMD has been very aggressive with the whole 5000 series pricing. It never cared to make the processors more affordable in order to gain some more significant market share.
While, the bitcoin mining bubble is no longer, so the share price is now well below $99. It was up to $160 some months ago...

But the Performance Optimizer for 3D V-Cache is listed on the .txt on the Gigabyte BIOS. And it's also mentioned before you download the driver on the Asus TUF B550 MB. I can't seem to find that on the MSI BIOS(Beta) on this Review

 

[Kovoet]

Right I'm replacing my CPU I guess. Keep the 5900 spare

I don't think you will see a difference.

As expected, the gains from extra L3 cache is hit and miss, since it has to sacrifice some clock speed.
I would be interested to see a more deep-dive into frame time consistency with this chip to see if there are significant gains there, because if so, those will be noticeable to the end user.

But for those of you who are disappointed, as I've been saying; adding L3 cache is not going to help performance across the board, it mostly affects instruction cache misses, which programmers know are mostly associated with poorly written software. So most heavy applications wouldn't see significant performance gains here (as they are better written), and you wouldn't see a multithreading boost as some of you expected either.

But Borderlands 3 and Far Cry 5 are SO WELL code... ah yeah... ok.

 

[TheDeeGee]

Even warmer than the 5800X and that's bitch to keep cool already.

 

[thunderingroar]

would love to see how this one performs in some of the heavier emulators like RPCS3 and compared to ADL

hopefully zen4 also gets this 3D vcache

 

[ARF]

Yeah, high gains means poor code

 

[efikkan]

In case I wasn't clear enough;
Instruction cache misses are mostly associated with (poor) software design, so in simplified terms; the worse the software, the more gain is to be expected from extra L3. Get it?

I was actually agreeing with you. But yes... I do get it.

 

[Crackong]

Impressive!

It is just running at 4.5GHz and beats competitor's 5.2 / 5.5

There is indeed a driver for optimizing 3D V-Cache in that driver package.

The performance Optimizer that everyone is talking about is this. What you have listed above is a bios that supports 5800X3D and has some performance improvements which are two separate things. The bios that W1zzard used is V2 1.2.0.6 c so it should be the same as what is listed there.

 

[zlobby]

is like, everything about it locked? cant change any voltages at all? like, the IOD ones related to memory/fclk, they shouldn't hurt the 3dcache no

Very sad, indeed. /s

I asked over on reddit but might as well ask here. Any idea if that is just a dud mc or is it another X3D limitation?

I think it's an early AGESA or a X3D limit.
