AMD shows Ryzen 9 3950X, 3rd Gen Threadripper

AMD announced this week a trio of new processors that run the whole gamut from starter chip to high-end beasts. AMD detailed what its 3rd-gen Threadripper will look like, showed off the new Ryzen 9 3950X, and even released a new Athlon APU, the 3000G.

Ryzen 9 3950X

The Ryzen 9 3950X is the one most of us are going to be eyeballing. The 3950X is a 16-core, 32-thread AM4 CPU. If you already have an AM4 motherboard, this chip will slot right in there provided you have the latest BIOS update. The 3950X offers a 3.5 GHz base frequency, and a 4.7 GHz maximum boost. It also has a 105W TDP just like its 3900X sibling. The chip has 512KB of dedicated L2 cache for each core, 64MB of shared L3 cache; That’s 72MB of total cache. That’s 25% more L2 cache when compared to the Ryzen 9 3900X.

AMD offered up some performance numbers for us to peruse, too. The company says the 3950X is 22% higher in single-threaded performance when compared to its own Ryzen 7 2700X in Cinebench R20. Meanwhile, on the multi-threaded side, AMD compared it to Intel’s big boy, the Core i9-9900K, and says their chip is 79% higher there. Gaming performance should be on-par with the 9900K, too.

Like Intel’s 9900K, AMD says the 3950X is optimized for liquid cooling and recommends at least a 240mm x 150mm AIO cooler to go with this chip.

The Ryzen 9 3950X will retail for $749 USD starting November 25.

3rd-Gen Threadrippers Revealed

AMD also talked about its high-end desktop processors, the 3rd generation of its Threadripper series. The series will debut with two chips: the Threadripper 3960X and Threadripper 3970X.

The 3960X is a 24-core, 48-thread chip with a 3.8 GHz base clock that boosts up to 4.5 GHz maximum. and 140MB of L2 and L3 cache combined. That one is going for $1,399.

The 3970X, meanwhile, is a 32-core, 64-thread monstrosity with 3.7 GHz base clocks and 4.5 GHz boost. Take a deep breath before you read the price: $1,999. Like the 3950X, these will be available on November 25.

They’re both sTRX4 socket chips that are compatible with AMD’s TRX4 chipset and motherboards. While it does use the new socket, the new Threadripper will be backward compatible with TR4 cooling solutions. Any cooler or waterblock you used with your TR4 Threadripper should make the jump if you decide to upgrade. Compared to the Ryzen chips above, the 3rd-Gen Threadripper will be a power-hungry chip, with a TDP of 280W.

AMD says the sTRX4 Threadrippres have a quad-channel DDR4 memory interface that can handle up to 2TB of memory. The chips have a total of 64 PCIe 4.0 lanes, with 48 dedicated toward PCIe x16 slots, 8 toward the chipset bus, and 8 lanes that can be dedicated toward a pair of NVMe slots, x4 onboard devices (Ethernet, WiFi, USB, etc), or additional SATA ports.

ECO mode

AMD also talked about its new ECO mode, which will come to all AM4 processors with Zen 2 cores. In short, it’ll let you configure the maximum power draw in AMD’s Ryzen Master software so that you can crank down the performance when you don’t need all that juice. AMD picks on its new 3950X chip to demonstrate the effectiveness of this feature; turn ECO mode on and you’ll see 77% of your performance with an impressive 44% less power draw and an estimated 7°C lower temperatures.

AMD Athlon 3000G

You wouldn’t want all that CPU power to leak out the bottom, though, and so AMD also revealed its Athlon 3000G. This 12-nm chip combines 2 Zen+ CPU cores (4 threads total) and Radeon Vega 3 graphics with 3 Vega Next-Generation Compute Units (NGCU). The CPU has a base clock of 3.5 GHz, and AMD is offering an unlocked base-clock multiplier. In other words, this thing is meant to be overclocked. The price seems to confirm that – the 3000G will be just $49 when it comes out on November 19.

So is the 3000G the same die as all the other Ryzen G chips, or have they made a smaller one?

any way to view old site theme? this new one is just aweful, I haven’t checked site in weeks or months, as soon as new theme popped up I lost interest, this used to be favorite news site.

Unfortunately the site was running a bespoke CMS, which was retired (in favor of WordPress) when the new owners took over last summer. The old site theme is no longer available, nor is it likely to be in the future.

1.3x ECO performance = full performance
square of the performance = 1.3 x 1.3 = 1.69
1.78x ECO power = full power

What makes ECO look good makes the turbo speeds look bad.

Higher than ECO performance sits in the steep OC range of W2 > sqr(F2/F1) x W1
F1 = MHz lower speed
W1 = Watts at lower speed
F2 = MHz higher speed
W2 = Watts at higher speed

Chuck is back at the NSA working really hard to demystify the new TechReport UI. It says a lot when even the best at the NSA is having trouble with new look an feel.

Intel called. It wants its chips breaking backwards compatibility with older sockets backed…. Oh wait a minute.

To be fair, they’ve been pretty good with the AM4 stuff (and AM3/3+ before it). Heck, AM3 chips would even work in many AM2+ boards, which was a neat trick since it was a different DRAM generation.

Now if they could only convince motherboard makers to always use flash chips large enough that you don’t need to have different UEFI installed depending on processor generation…

It happens, after 20 years of ol’blue the fresh new look isn’t a bad thing either. Looks sharp and modern. I”m a fan if it keeps TR focused on news and reviews.

28-core, 48-thread chip

I think that’s a typo! Do you mean 24-core?

Yep, it’s a 24-core, 48-thread part.
