Ryzen 7 7800X3D: Ahead of Core i9 for gaming at 40% power draw

Extra tests, Processors | | Ľubomír Samák

The most popular Ryzen 7000 with 3D V-cache obliterates competition in its targeted environment. Intel doesn’t measure up to the Ryzen 7 7800X3D in a comparable price range in terms of speed, and even if someone disregards price and sees the Core i9-13900K(S) as a an apt competitor, when comparing power draw, everyone’s appetite for Intel will go away. Their efficiency is… incomparable, as each is at a different end of the spectrum. Read more “Ryzen 7 7800X3D: Ahead of Core i9 for gaming at 40% power draw” »

AMD quietly launches big.LITTLE, Zen 4c-based Phoenix2 confirmed

News, Processors | | Jan Olšan

Many like to diss Intel for hybrid processors but leaks has long been showing that AMD is also preparing their own take on it – the “LITTLE Phoenix” or Phoenix2 APU, to be used in cheaper mobile Ryzen 7000 SKUs. Phoenix2 is to feature Zen 4 big cores and Zen 4c as little cores, which is a compact redesign recently introduced in servers. Now this hybrid SoC has indeed appeared and AMD has officially confirmed it on their website. Read more “AMD quietly launches big.LITTLE, Zen 4c-based Phoenix2 confirmed” »

Ryzen 5 5600X3D launches this week, but exclusively in the U.S.

News, Processors | | Jan Olšan

AMD is reportedly going release a new AM4 processor after more than a year, a cheaper derivative of the Ryzen 7 5800X3D called Ryzen 5 5600X3D, which would include the game-boosting 3D V-Cache, but with only six cores. Initially, there were some doubts, but it looks like it is real. Its release and availability in the US is already confirmed to be due this week. It’s less clear for the rest of the world, however.

big.LITTLE by AMD: Zen 4c has the same IPC as the big Zen 4

Analysis, News, Processors | | Jan Olšan

After Intel’s hybrid CPUs, AMD is preparing its own big.LITTLE scheme that uses a mix of Zen 4 cores and a new Zen 4c variant that will be used in servers but also in laptops. However Zen4c is and at the same time is not a little core. While having much smaller footprint, it is said to be fully architecturally equivalent to the large core, including (almost?) the same performance per 1 MHz. The only little thing about it is clock speed. Read more “big.LITTLE by AMD: Zen 4c has the same IPC as the big Zen 4” »

RDNA 3 the same as RDNA 2? Wrong, computational tests show

Analysis, Graphics | | Jan Olšan

We’re still in the process of finishing our review of the Radeon RX 7600 (the Pulse model by Sapphire), but we made a little preview, looking at a subset of tests that might go unnoticed in the final review: compute applications benchmarks. Why? The card seems to show better than typical performance gains in them. We’ve seen opinions stating that Navi 33 GPU bingst nothing new versus the Navi 23 chip, but these results say otherwise.

AMD, like Nvidia, will produce chips at Samsung, on a 4nm node

Graphics, News, Processors | | Jan Olšan

Against expectations, Intel will start manufacturing processors at TSMC. Similar diversification may occur with AMD, who relied almost entirely on TSMC lately. But according to unofficial reports, the company will start manufacturing some of its chips at Korea’s Samsung, much like Nvidia recently did with some of its GPUs. This would reduce AMD’s dependence on a single supplier, but the move likely seeks to cut costs, too. Read more “AMD, like Nvidia, will produce chips at Samsung, on a 4nm node” »

AMD fixes bug that kills Ryzen 7000 CPUs, update your BIOS

News, Processors | | Jan Olšan

Last week, cases of destroyed V-Cache using Ryzen 7000 “X3D” CPUs and even a burned socket on the board (the dead CPU probably started drawing excessive current from the VRM through the pins). At first it wasn’t clear if it wasn’t a result of manual overvolting, but AMD announced that they have found the cause of the problem and are releasing board BIOS updates to protect the CPUs from damage, so definitely update.

Radeon RX 7600 XT launch date leaked: less than four weeks away

Graphics, News | | Jan Olšan

A few days ago, reports started surfacing that more affordable Radeon graphics cards with RDNA 3 architecture based on the Navi 33 chip might finally be coming to market. They stated that these cards could be exhibited (just that at that point) at Computex 2023 during (May 30–June 2). But it might all happen faster. According to information posted by YouTuber Moore’s Law Is Dead, there card should be available on the shelves before then.

Radeon power draw finally stays low with multi-monitor setups

Extra tests, Graphics | | Ľubomír Samák

In a multi-monitor setup, graphics cards naturally have higher power draw, and in some cases significantly so. But it seems that, at least with the RX 7900 XT (Sapphire Pulse), this is no longer the case. We know from measurements that the increase in power draw of this card is very low, several times lower than it used to be in the past in all the older models we have tested. Basically, we can say that the “problem is solved”. Read more “Radeon power draw finally stays low with multi-monitor setups” »

AMD’s Zen 6 processors will use 2nm process technology

News, Processors | | Jan Olšan

Few days ago there was news that GeForce RTX 5000 graphics (the Blackwell architecture GPUs in them) will not yet use the 3nm manufacturing node, reportedly staying on 4nm technology instead. Now, there is news about another product that will use a new technology for a change – AMD processors with Zen 6 architecture. We learned that thanks to one of the employees leaking this important detail on the LinkedIn social network. Read more “AMD’s Zen 6 processors will use 2nm process technology” »

A620 chipset specs in detail: a PCIe Gen4 uplink surprise

Motherboards, News | | Jan Olšan

Last Friday, the last day of Q1, low-cost AM5 boards for Ryzen 7000 processors based on the low-end A620 chipset were released by all the manufacturers in a coordinated fashion (we’ve put together an overview of the models here), but AMD itself didn’t make any announcements at first, so we didn’t have exact specs. These have been published now and include one surprising thing which makes the A620 better than expected. Read more “A620 chipset specs in detail: a PCIe Gen4 uplink surprise” »

Cheap A620 AM5 boards are out, starting at $85. Here’s the models

Motherboards, News | | Jan Olšan

In the last few days, inexpensive A620 chipset-based AM5 motherboards for Ryzen 7000 started leaking. We’ve already seen photos of one model and it seems that AMD has timed the unveiling and release for the last day of March (maybe they wanted to formally make it before the end of the first quarter). And now, boards with this chipset were launched from all the usual manufacturers, with the cheapest ones going as low as $85. Read more “Cheap A620 AM5 boards are out, starting at $85.

First AMD FSR 3.0 sneak peek, technology is similar to DLSS 3

Graphics, News, Technology | | Jan Olšan

Few months ago, AMD has announced ongoing work on the third generation of FidelityFX Super Resolution (FSR) upscaling, which should bring a similar feature to DLSS 3 – interpolating of intermediate frames inserted between legitimate game frames, much like TVs do with video and movies. AMD has now formally confirmed this and presented FSR 3.0, which will offer frame interpolation and will again be open technology (including source code).

Radeon RX 6300 spotted in China. Modern GT 1030 replacement?

Graphics, News | | Jan Olšan

Basic low-cost dedicated GPUs became a dying breed over the last decade. Faster integrated GPUs leave less and less room for them and it doesn’t pay off to develop new chips of this sort anymore. Nvidia has been selling the GeForce GT 1030 with a 16nm Pascal architecture chip for almost six years now, and it’s only now, it seems. that a more modern replacement could appear: the Radeon RX 6300 with a 6nm GPU based on a current architecture.

24GB/48GB DDR5 modules don’t work with Ryzen CPUs, fix coming?

Memory, News, Processors | | Jan Olšan

In the past, Intel processors could not run newer higher-capacity DDR2 and DDR3 modules, while AMD processors worked. That’s why we were sort of assuming that the currently appearing DDR5 modules with unusual “non-binary” capacities would just automatically work on AMD platforms. But that’s not true, it seems that they only work with Intel processors for now and Ryzen 7000s will only be able to use them after a future update.
