FSR 2.0 is no eyesore now. AMD upscaler analysis in Deathloop

The second version of FidelityFX Super Resolution is officially released. This upscaler premiered in Deathloop, the first and so far the only supported game. We compared FSR 2.0 with FSR 1.0 in our tests, both visually and performance-wise. While FSR 1.0 couldn’t compete visually with Nvidia’s DLSS, and the result was significantly worse, AMD pulled the thorn out of its heel with FSR 2.0. A full-featured alternative is now available.

PWM vs. DC control. Why do fans work better with impulses?

We avoid it like the plague when it comes to backlighting LCD monitors, but we can’t imagine the best fans without it. We’re talking about pulse-width modulation for voltage regulation. In this article, we will explain in the simplest possible terms the reason why PWM regulation is gradually replacing linear regulation. Related to this in computers is the strong disproportion of 3-pin to 4-pin fans, of which there are considerably more. Read more “PWM vs. DC control. Why do fans work better with impulses?” »

N4X: TSMC unveils special processes for high performance chips

Five to ten years ago, Intel had been the undisputed king of silicon processes, but the delay of 10nm node has ended that and TSMC has been the clear leader since. It is often said that its processes are specialised for mobile use, still remaining inferior to Intel in terms of the maximum achieved clock frequency. But this might change soon. The company will now focus on this very area and high performance chips for PCs. Read more “N4X: TSMC unveils special processes for high performance chips” »

First OptiNAND-based WD HDDs go on sale. 20 TB without SMR

HDD capacities have been rising slowly lately and new larger HDDs often take very long to ship after being announced. But it looks like we are finally getting somewhere: the first 20 TB capacity HDDs (without SMR) are coming, from Western Digital. They’re actually coming to the market with general availability. What’s more, they are interesting because they are the first drives with the recently introduced OptiNAND technology. Read more “First OptiNAND-based WD HDDs go on sale. 20 TB without SMR” »

Samsung will start 2nm chip production 3 years after 3nm node

Samsung’s semiconductor production has been a center of negative news lately. Apart form delays, Samsung processes are believed to be inferior to TSMC node-for-node. But despite this Samsung is still the number two in leading edge process nodes out of the Foundry producers. Now the company has announced 2nm node, which should go into production in four years, two to three years after the volume ramp of the 3nm technology.

Nvidia shares experimental new DLSS models for public testing

The version of Nvidia DLSS integrated in games can be upgraded manually by replacing DLL files by newer and better ones from another game. TPU has an archive for various versions extracted from games, but there’s an even better opportunity to tweak the upscaling quality in games now: Nvidia will offer development DLSS models for testing directly, this will allow you to try even the newest pre-release experimental versions.

OptiNAND: WD adds flash memory to HDDs, but not in the SSHD way

Lately (actually for several years now) we’ve seldom had news about hard disks. An opportunity to write about a new innovation in this area has come now though. Western Digital has introduced OptiNAND technology, which improves the performance of mechanical drives by integrating NAND Flash memory – but not in the way of SSHDs, which only used it for caching. OptiNAND serves other purposes, and it could be much more useful. Read more “OptiNAND: WD adds flash memory to HDDs, but not in the SSHD way” »

TSMC keeps rocking. 4nm process to be ready a quarter earlier

When release dates get rescheduled in computer industry, it’s usually to later. Obstacles in development happen and it is not always possible to meet the plans, so delays are common. But there’s a good news of this sort now, for a change. TSMC actually managed to push the development of ab upcoming future process noe forward. The company has now announced that the production of 4nm chips will start earlier than originally planned. Read more “TSMC keeps rocking. 4nm process to be ready a quarter earlier” »

AMD redies 3D chiplets: demo of Zen 3 with 192MB 3D V-Cache

After Intel, AMD has now presented its new products. These include the Ryzen 5000G APU, Radeon RX 6000M graphics for laptops and FSR upscaling intended as a competition for DLSS from Nvidia. But the processor news was the most interesting thing: 3D silicon chiplets layered on top of each other may come into Ryzen processors, and AMD has shown a prototype, which has 3× larger L3 cache, bringing nice gaming performance boosts.

A look at Nvidia DXR, Broadcast App and DLSS visual quality

We are introducing a new testing methodology for graphics cards. One of the reviewed cards will be the GeForce RTX 3070 and we have an interesting one: Aorus GeForce RTX 3070 Master 8G with six video outputs. Before the review comes out, we’ve use it for a visual comparison to see the impact of ray tracing and how the different DLSS settings in the latest Cyberpunk 2077 patch will affect the quality of the game graphics.

Ampere deep dive: what’s new in GeForce RTX 3000 architecture

In terms of hardware, September was a green month with the release of the new generation of Nvidia GPUs, GeForce RTX 3000. They are based on the new Ampere architecture. In this article we are going to discuss what’s new compared to Turing: the new SM architecture doubling the number of shaders, the manufacturing process and the characteristics of the two chips that have been unveiled so far.
