High-End Desktop? What’s That?

The Ryzen 9 3950X Comes Into View

As teased at E3 and seemingly every show that AMD has been to since, we’re now ready to get our hands on AMD’s top-tier consumer-grade processor. The Ryzen 9 3950X is the bigger cousin to the Ryzen 9 3900X, this time using two 8-core chiplets built on TSMC’s 7nm process with the Zen 2 microarchitecture. This is paired with the same I/O die, and overall this Ryzen 9 3950X will offer four more cores and +100 MHz on the turbo frequency over the 3900X, all at a $749 recommended retail price point.

The Ryzen 9 3950X will be compatible in the majority of AM4 motherboards, although in order to take advantage of the 24 PCIe 4.0 lanes on the CPU, an X570 motherboard is recommended. The 16 cores offer a 3.5 GHz base frequency and a 4.7 GHz single core boost frequency; the overall all-core turbo frequency will be dependent on the motherboard used, the quality of the silicon, and the turbo in play.

The 105W TDP matches that of the 12-core part, and it should be noted that the 3950X will not come with an in-the-box cooler. Instead, AMD argues that customers looking at this price range of CPU typically go out and purchase their own, something better than the 125 W Wraith Prism that AMD might have put in the box. To that end AMD is going to publish a list of recommended cooling solutions that are pre-validated by AMD on the website, which should be live on today (the 7th).

Regarding BIOS and AGESA versions on motherboards: AMD has stated that AGESA 1.0.0.4B (also known as 1.0.0.4 Patch B) is going to be required in order to enable full performance on the Ryzen 9 3950X. AMD stated that this AGESA version actually unites several different groups of Ryzen CPUs under the same numbering scheme, to make it easier to manage. It is worth noting that when quizzed, AMD acknowledged that some motherboard manufacturers were putting out ‘beta’ versions of 1.0.0.4B, rather than the full release, and they recommend that users should wait for a full 1.0.0.4B version for their motherboard (even though some motherboard manufacturers aren’t exactly being clear).

In terms of performance, AMD claims a +22% single thread performance jump for the 3950X over the 2700X, in 1080p gaming the company claims it goes toe-to-toe against the Core i9-9900K and trounces the Core i9-9920X (a $1200 CPU), and in content creation it surpasses both the 9900K and 9920X by 18-79% in selected tests. The company also states that a 16-core 3950X uses less wall power than an 8-core 9900K system.

With Intel cutting its upcoming Cascade Lake-X HEDT processor line in half (and conveniently not releasing a 16-core part), the field does get a little more competitive for anyone looking at building a holiday system. What is important to note here is that AMD is shifting the line between consumer and high-end desktop higher: users spending $749 on a CPU get a ton of cores, but if they need more PCIe lanes, they have to go even higher to get the latest and greatest (see 3rd Gen Threadripper below). On a different note, AMD did state that Intel’s recent price adjustments had no effect on its product plans.

One side announcement from AMD, regarding all of the Ryzen 3000 hardware, is that every CPU now supports a cTDP down mode through the Ryzen Master software. With the tool, users can select the next power range down from the TDP of the processor. This means that 95W/105W CPUs can be set to run at 65W, then the 65W CPUs can be set to run at 45W, and the 45W CPUs can run at 35W.

AMD is doing this because they have seen a number of customers request high-core count processors at lower TDP values. Rather than releasing a wide array of X and non-X parts to satisfy all different areas of the market, AMD is offering this ‘cTDP down-like’ option for system builders that do want to focus on something like a 65W 16-core processor for their system. This isn’t to say that AMD will not release non-X CPUs in the future (they’re typically cheaper than the X CPUs), but rather than have customers wait for those parts to enter the market, AMD is giving this option to speed up adoption.

    Almost nothing. These things are for work. A reasonably fast quad core (anything Ivy Bridge or newer, really) is fine for almost any casual programs. Going up to eight cores makes sense for gaming since the new consoles will be eight core. Reply

    The consoles have been 8 core since 2013 dude. PS4 and xbone are 8 core. 8 slow cores, which should have prompted swift acceleration of multi threaded game engines.

    Yet here we are.

    Half of this console generation Intel was in the lead and they kept milking the core count. Until 3,4 years ago they were selling dual core cpu as i7 on mobile. It wasn't until AMD came up and basically showered everyone with 4 and 6 core cpus for half the price is when Intel dropped the BS and started offering real 6 core cpus in the lower tier consumer market and 4 core real 4 core cpus in mobile etc. I blame only Intel.

    And we saw slow progress toward multi-threaded games throughout the generation. There are way more games today that can take advantage of 4+ cores than there were in 2013. It takes time to adapt game engines and not every kind of game will even benefit from more cores. All I'm suggesting is that if you play games you have some reason to go beyond four cores. Reply

    Consoles were based off jaguar, which really had 8 half cores that shared execution units. So really, 4 cores. Reply

    You're confusing Jaguar for Bulldozer.

    Jaguar uses complete cores, albeit "small" ones in terms of area - in design and performance terms they're somewhere between the old K8 Athlon 64 and K10 Athlon II processors.

    I think the confusion comes in because the console implementation of Jaguar has 8 cores split across 2 "modules" which is the same terminology used for 'dozer, but referring to a different thing:
    Bulldozer module = 2 cores with shared FP resources
    Jaguar module = 4 independent cores, like a CCX in Zen

    8 cores at 1.6GHz (PS4 as the slowest) is at best the same as 4 cores at 3.2 GHz, assuming everything else equal and perfect MT. Plus those cat cores were essentially half as capable as the current stuff, normalized by clock. Therefore, consoles have about the same as 2 proper desktop cores - the lowest end CPUs you can buy.
    Anyway, there are many games that use more than 4 cores these days. Especially stuff coming out now when also Intel started offering more cores and AMD having competitive if not superior chips.

    Casual everyday users absolutely do not need such CPUs. Reply

    Exactly right. Core count is the new Mhz race for the uninformed. Reply
