It's well known among enthusiasts that AMD's Ryzen processors benefit tremendously from high memory clocks, especially in multi-threaded applications. This isn't down to the memory bandwidth increase (although that can help), but more about the increased clock rate for the CPU's Infinity Fabric. That...

Memory overclocking performance has historically been a weak point of AMD's Ryzen processors. This is true even on Socket AM5; where Intel-based DDR5 rigs can hit 7000, 8000, all the way up to the world record of 11,202 MT/s, AMD systems tend to struggle to get much past 6000 MT/s. On the Socket AM4 platform, memory...

AMD hosted its Data Center and AI Technology Premiere in San Francisco, CA today, where it outlined its vision and strategy for the future of computing. The company introduced its first batch of fourth generation EPYC 9004 series server processors, aka Genoa, last November which largely delivered on the promise of...

AMD has pulled back the curtain on its Ryzen 7 7800X3D and finally given us a preview of the chip's highly-anticipated gaming performance figures. The results do not disappoint. In two new official AMD slides revealed, the 7800X3D completely dominates its arch-rival, the Core i9-13900K and its predecessor the Ryzen 7...

If you saw our story yesterday about Ryzen 7000's one-DIMM-per-channel memory speed limitation, then you may have had the same brainwave we did: what does this mean for Ryzen's Infinity Fabric? On extant Ryzen processors, lowering the memory speed usually reduces the speed of communications within the...

We always caution folks against putting too much stock in manufacturer numbers. Companies always want their product to look like the best, right? Now, AMD's been pretty honest after getting burned by spurious marketing in the past, but recentRyzen 7000 numbers look pretty darn good. So, what's the catch?
We won't...

If you're reading this, you're probably a PC hardware enthusiast, and if you're a PC hardware enthusiast, there's a strong possibility you've built a Ryzen system recently. AMD's Ryzen processors have become very popular, particularly in the DIY market, and that's despite a couple of quirks you have to be careful of...

You've probably heard that tech companies have stopped hiring lately. This is true of Apple and Google, but it's not universal. AMD is hiring, and even building a new campus for its Radeon Technology Group division.
Older hardware enthusiasts will remember that the Radeon Technology Group started life as Array...

The Ryzen 7 5800X3D is an enticing chip for gamers because AMD stacked on a pile of 3D V-cache, effectively greatly increasing the amount of L3 cache (to 96MB total). More L3 cache can have a measurable impact in gaming, as we showed in our Ryzen 7 5800X3D review. The downside is AMD also locked the CPU so that...

On Socket AM4, it took a few generations for AMD to get its memory controller performance all maxed-out. The original Ryzen struggled with DDR4 memory faster than about 2667 MT/s, and it wasn't really until Zen 2 (the Ryzen 3000 series) that we started to see wide support for memory faster than 3000 MT/s.
That's...

When we tested the Ryzen 7 5800X3D, it came out ahead of the Core i9-12900K in every gaming benchmark. You've probably already heard that story, but you may not have considered the implications: Intel's Alder Lake CPUs are double-digit-percentages faster than AMD's original Zen 3-based Ryzen 5000-series processors...

Hardware enthusiasts will already know, but for anyone who doesn't, the performance of AMD's extant Ryzen platforms is seriously impacted by the transfer rate of the system RAM. It's not actually the memory bandwidth that matters for most tasks; instead, it's because the speed of the "Infinity Fabric" is...

AMD's Ryzen 7 5800X3D achieves incredible performance uplifts in certain applications by "simply" adding an extra 64MB of cache onto a Ryzen 7 5800X. We put "simply" in quotes because the vertical die stacking process employed on the chip is still cutting-edge stuff, and AMD had to make significant concessions to the...

While the conventional wisdom has been that overclocked memory offers minimal performance gains, that's just not the case. Faster memory, whether it increases clock rate, reduces latency, or both, can have a significant effect on system performance. It's most noticeable in apps like video encoding and compression, as...

Back in the 1990s, NVIDIA got its start selling graphics adapters for desktop PCs. After a rocky start with the NV1, NVIDIA established itself as a performance leader soon thereafter with the release of the TwiN-Texel (TNT) chip, and with the original GeForce 256, as a technology leader, too.
That's all ancient...

For chip companies, bigger profit margins can be found in the data center market, and that's often where we see new innovations manifest first before trickling into the consumer space. To wit, we know AMD is prepping a Zen 3 refresh with stacked 3D V-cache. While we patiently wait, AMD today also just introduced 3rd...

Since 2020, Netflix has been able to serve up 200 gigabits per second (Gbps) of TLS-encrypted video traffic from each of its servers, but there is now a path to doubling that amount to 400Gb/s. Andrew Gallatin, a senior software engineer at Netflix, outlined how the streaming service has been able to achieve the feat...

EVGA and its overclocking partner Vince "Kingpin" Lucido are not finished teasing the upcoming X570 Dark motherboard for AMD's latest generation Ryzen processors. In another Facebook post, Lucido showcased what he was able to achieve when pairing the X570 Dark with a Ryzen 3 5300G APU and throwing liquid nitrogen into...

Are we enjoying the Chip Wars of 2020 yet? Things are just getting started, folks. AMD is talking a big game about Zen 3 and its Ryzen 5000 series, which will debut to retail next week. More than just lip service, multiple leaks suggest AMD has a real winner on its hands. This is evidenced yet again in a validated...

How often have your heard that patience is a virtue? Forget that noisewhen it comes to GPU launches (and technology in general), the leak and rumor scene thrives because there is so much interest in what is right around the corner. In this case, AMD is just a few weeks away from unveiling its Radeon RX 6000 series...

Most of the focus in the PC space recently has been on new graphics card, with NVIDIA launching its GeForce RTX 30 series and AMD prepping its upcoming Big Navi release. But what about CPUs? As AMD has said time again, Zen 3 is on track to launch this year. And if the latest rumor is true, one of the upcoming CPU...

Just last week, it was reported that AMD's unreleased Ryzen 7 4700G had hit a 4.7GHz all-core overclock, as depicted in a benchmark leak. Good stuff, but can someone do better? Well yes, yes they can. The all-core overclock to beat now stands at 4.8GHz, or 4,815.24MHz to be precise, though we do not know if that was a...
