AMD Ryzen 9 7900X3D Drops to $409, to Clash with Core i7-14700K

[btarunr]

AMD Ryzen 9 7900X3D is the often-ignored middle child of the 7000X3D series that's flanked by the reigning gaming CPU champion, the Ryzen 7 7800X3D; and the company's flagship Ryzen 9 7950X3D, which performs within 5% of the 7800X3D in gaming, but with the added 8 cores shoring up its productivity performance against the Core i9-14900K. Pricing of the 7900X3D dropped to $409 on Amazon, which is a huge departure from its $600 launch price. At this price, the 7900X3D is set up for a direct clash with the Intel Core i7-14700K, which is going for $400, with its iGPU-disabled sibling, the i7-14700KF listed at $392.

The Ryzen 9 7900X3D is is a 12-core/24-thread dual-CCD processor, with its 12 cores spread among two CCDs in a 6+6 configuration. The first of the two CCDs has the 96 MB L3 cache thanks to the 3D Vertical Cache (3D V-cache) technology, while the second is a regular CCD with just the 32 MB on-die L3 cache, but which can sustain higher clock speeds than the 3D V-cache CCD. The similar 16 core 7950X3D flagship can be had for $600, or about $50 higher than the i9-14900K, while the 7800X3D is going for $370.

Nice price cut for Americans. Should be interesting if we get a discount in Europe as well.

As someone who owns this chip I will tell you why this is better than the 7800X3D and 7950X3D. Heat output. You see the 7900X3D does not go above 80 degrees for me. That allows it to maintain a nice boost clock. I know the argument will come about it being a 6 core but that does not matter I am going to link 2 HW info screenshots.

This is after a nice session of Gaming, including TWWH3, The Gunk, AMS2 and Aliens Fire Team

As you can see all cores were loaded at 100%. Then you can see that all cores have average use at the lowest 1.4% to 11.8%

Conventional wisdom says they are clearing inventory for the upcoming Zen 5 launch. And indeed that’s what I think is happening here. But such moves aren’t always the case. In an uncompetitive environment, companies will never drop prices no matter how old the product after launch. This is what happen with Intel processors during the bulldozer and a little after years. A five year old Core i9 for instance would have the same launch price.

I for one am happy that those days are gone. Now you can buy a good processor from yesteryear at a bargain.

This is discounted because it's unpopular and has some downsides, mainly being six useful cores for gaming and six for everything else.

Price finally reflecting its worth. A 7800X3D is faster in any game, and a normal 7900 (still a 6+6 unfortunately) is faster in everything else.

A 14700K is still a better buy IMO, but at least the price is in line with reality now.

Supposed temperature advantanges of this SKU are irrelevant. All the X3D chips run cool anyway it's not unique to the 7900.

We'd see price cuts across the board if that were true, this is discounted because it's unpopular and has some downsides, mainly being six useful cores for gaming and six for everything else.

Prices are down from launch on Alder Lake, Raptor Lake, Zen 3 and other Zen 4 processors. Not just the 7900X3D as the article above states at least for the entire Zen 4 X3D lineup.

A 12900KS for instance goes for $479 on Newegg down from its $739 launch price. Intel processors always stayed at launch price many years after release in the bulldozer days.

That's just normal depreciation of non cutting edge computer hardware.

I don't think the Zen 5 launch is imminent or related.

A $40 difference between an eight core and a 12 core, but a $190 difference to the next good CPU that has just four more cores shows how much they want to get rid of these chips though, or how much more in demand the 7800X3D is.

Have you personally reviewed this chip? Since when does the 7950X3D run cool? One of the complaints about the 7800X3D is clock speed. Does a 7800X3D do 5.6 GHz on any core?

Not true. Intel processors between Nehalem and Kaby Lake stayed at launch prices until inventory ran out years after launch. The reason, no one wanted AMD processors at any price during those days. So it was either pay Intel launch prices of old processors or buy a new motherboard and latest Intel processor. The price did not depreciate.

Laugh at the truth. I see you have watercooling on your 7800X3D and 5.15 seems like a proud OC you have.

Yep this. Gaming is still a niche case. It's not productive and is the piss filled floating turds kiddy pool of computing. So the X3D is a cluster fuck for anybody doing anything even quasi serious on their computer. Even then the reality of PC gaming is it's the farthest thing from high end gaming or a master race. Most gaming PCs get blown out of the water by a modern console.

The X3D tech is cool and all but it's still a niche case. Intel did something similar back in the day and then abandoned it for good reasons. You'll also find at the super high end cache is often just disabled completely. In .nix based systems there's a handy command line for doing this as you often have to for reasons.

85 C instead of 80 C (under full synthetic blender load on an outdated air cooler) is completely irrelevant for a CPU that doesn't throttle until 90 C.

Clock speed is also meaningless when the CPU with a faster clock is still 5-10% slower in games, which is the point of X3D.

Not many reviewers bothered to look at the 7900X3D.

The second reason to buy X3D processors is efficiency. These chips run cooler due to better binning because they have to in order to support the cache up top. This appeals to users as well as the gaming use case. So the gaming niche argument losses a little more water.

They're certainly more efficient under full load, making them great for cheap coolers or SFF but Intel uses about half the power at idle and is comparable in low load. Should be fixed with Zen 6 as they're introducing new interposer tech to replace the costly (in power draw) IO die and infinity fabric. It's why you basically don't see less than 30-40 W at all times with Zen.

I mean pretty much all 7000 series CPUs will behave like this during gaming if the cooling is good enough.

They run cooler and more efficient simply because they run at lower clocks, they are not binned in any way, as a matter of fact if AMD was binning them these would probably of the worst quality because they simply do not need to clock as high as the rest.

It's not actually binning, it's simply that the cache enforced voltage limitation forces the chips to run much closer to their efficiency sweet spots, compared to the standard Zen 4 parts which try to max out frequency.

This is also shown in how late production 5800X3D chips are worse and run hotter than early production ones, since the good bins go to server chips, and just about any die will hit the target frequency anyway since it's so much lower than the standard parts non X3D.

Sorry tell the truth. The 7900X3D was not sampled. That is the reason the only tech review is a prebuilt on Kit Guru. I suggest you watch that. If you don't think that less heat can make an X3D chip run faster then why are you using such high end cooling equipment? You put that in there to prove my point thanks. It just proves that the 7900X3D does run cooler than the 7800X3D.

Simply because I have a 13 litre case (shoebox size) with no space for an air tower and my custom loop cools a 400 W GPU, not just my CPU.

I don't really care how "cool" the 7900X3D is, it's slower than the 7800X3D in the tasks it's designed for, that's what matters.

It is slower, but you never sampled it. That means you are entirely basing your opinion on what you believe.

I'm entirely basing my statement on reality, which is that the 7950X3D (better than the 7900X3D in every way) tests 5-10% slower than a 7800X3D in gaming. The 7900X3D doesn't magically leapfrog both of those chips with a core deficiency to boot.

In fact, it's slightly slower than the 7950X3D since it has 2*6 instead of 2*8 and clocks lower. This would make it the slowest of the three in gaming. Find me a test that shows otherwise if you want to make claims.

Even with that it is still entirely your opinion. It does not matter as it is faster than my previous chip (5800X3D) and that is the only thing that matters to me when I am trying to catch the Porsche 919 Evo using my AUDI in AMS2.

Is it opinion though?

As predicted. Slower than 7950X3D, which is slower than 7800X3D (in gaming).

It's good you're happy with your purchase but try and avoid claiming things that aren't true.

What is that when it says all test suite? I am not talking about 1080P but 4K. Any CPU can do well at 1080P at 4K is where you see the separation. It is not 2015. Windows knows how to handle DUAL CCDs quite well. I am basing this on my use of the 5900x before I got a 5800x3D. BTW thanks for proving that a $409 is faster than a $600 Intel chip. Translation, I am quite pleased with my chip and would recommend it for high end GPUs like the 7900 and 4080/4090 GPUs. I am not talking about software but raw performance to give me over 350 FPS in AMS2.

All test suite is simply the average of all games tested. You've also got it backwards, at 4K there's next to no difference between contemporary CPUs due to a massive GPU bottleneck, even with a 4090.

Here's proof.

Are you sure about that. I have been playing at 4K since this year began, are those numbers from Day one reviews? There have been updates to the micro code since then and MS have also done some refinement for Multi core CPUs. Using a 4090 means what? You do not get to use any of AMD software features that improve performance using an AM5 CPU with a Gen 5 NVME. You will probably tell me that Gen 5 NVME makes no difference too. I know that I feel a difference and at the end of the day that is all that matters. At $409 no one who buys this will be disappointed with it. It almost makes me want to send mine to TPU to show what it can do with a 7900 GPU but you can continue with your assessment as I am having too much fun to even contemplate that.
