The world's first 240 Hz 4K gaming display is now available for purchase.



Samsung has released the world's first 4k gaming monitor, which features a 240 Hz refresh rate and is unrivalled by any other.

It's called the Odyssey Neo G8, and the deep and realistic graphics make the gameplay enjoyable. It is the world's first gaming television, adding a new dimension to the gaming experience.

 According to a press release from Samsung, it is a significant first-of-its-kind breakthrough that makes gaming quick and simple.

It is now only available in a 32-inch format. The screen resolution is 3840 x 2160 pixels, and the fact that it is curved adds to the gaming experience. It makes advantage of the most up-to-date colour gamut technologies. Its aesthetics and music were created with video games in mind.



The screen refresh rate has been enhanced to the point that it now lasts up to one microsecond, allowing for smooth and even rotation of the fast rotating visuals. The game's speed isn't slowed down in any way. To lighten it up, the contrast and other elements have been increased.

After that, Corsyenc lighting is put on the back of the display, which recognises colours and deepens the scene based on the situation. As a result, a new display technology known as Matte Display has been developed.

The Evolution of Ryzen CPUs

 AMD has made a clear leap forward in terms of performance per Watt, already evident in the transition from Excavator architecture to Zen. With the subsequent evolutions of the Ryzen processors, AMD has offered not only greater performance but also a level of consumption that has remained virtually unchanged. I ask Robert Hallock what has changed internally in AMD, at the development team level, to be able to achieve such an efficiency leap forward. AMD is currently the only company that offers high-end processors and video cards on the consumer market. In the past among professional positions at AMD there has been a lot of work related to the world of video cards.



Making predictions on the market success or otherwise of Intel ARC proposals means trying to predict an unclear future, but difficult not to share Hallock's reflection. Building video cards is extremely complex and expensive work, for which AMD and NVIDIA can boast an experience that Intel does not currently boast. What technology would you most like to have available in 5 years' time - a smartphone with a folding screen that can be compact and at the same time provide a large display in order to increase productivity? AMD's answer is not obvious, but it is the AMD Radeon R9 Fury X card, which first saw the adoption of High Bandwidth Memory. Products of this type, if and when they are available, will not take the place of a traditional PC in terms of flexibility and processing power but will represent an even more complete work and entertainment tool than they are now.

Chinese processors protect Russia from sanctions and the shortage of Intel Core and AMD Ryzen processors.

 Sanctions against Russia are tough, even from a logical standpoint. As evidence, the sale of Dannie's new motherboard with KaiXian KX-6640MA demonstrates that the market is being forced to transition from Intel Core and AMD Ryzen to Chinese processors.

Intel and AMD are two of the four companies with the right to design and sell chipsets based on the x86 microarchitecture. As this duo has been responsible for the sale of a substantial portion of this type of CPU for years, Russia has been adversely affected by the withdrawal of their products, as it is impossible to find replacements to Intel Core or Ryzen given the current state of technological innovation.

However, alternatives exist from a side that is not as actively committed in sanctioning Russia. We are discussing China and companies such as Zhaoxin, which designs and distributes a line of KaiXian CPUs for usage primarily in China. The KX 6000 series, which was launched in 2019, is the most recent CPU family in this category.

CPU Benchmark evaluated a four-core, four-thread version of the chip running at 3GHz with a 70W TDP, and it scored 1,566 points for multithreaded operations on CPU . Core i3-12100F scores 14,427, while Ryzen 5 5500 scores 19,885. Similar performance gaps exist for single-threaded operations: 722 points versus 3,525 for the Core i3 and 3,084 for the Ryzen 5.

The specifications show that these processors are much inferior to AMD and Intel's current offerings. Although it does not appear that Russia will be fully cut off from computer hardware at this time, the sanctions will undoubtedly impact not only players but also technology companies owing to the lack of access to Xeons and EPYC processors.

If you believe the performance disparity is significant, the issue is actually far worse. The Dannie processor is designed for both desktop computers and laptops, hence its TDP is limited to 25W and it will operate between 2.1 and 2.7GHz. Dannie chose a processor with eight cores, which offers it at least one advantage above the processor with four cores that was graded higher.

AMD Radeon RX 6950 XT and RX 6750 XT

 AMD has released three video cards from the RX 6000 family . Existing processors are utilized, but with faster memory and changed software, the RX 6950 XT, RX 6750 XT, and RX 6650 XT should stand out from the video cards that come after them.

Higher clock speeds on the same chips



Although there are increasing rumors regarding the next generation of video cards, this hasn't stopped Nvidia and AMD from launching faster models late in the current generation's lifecycle. The RTX 3090 Ti, a maximally screwed-up Ampere card that stood out mostly owing to its huge energy consumption, was just released. This time it's AMD's turn, which uses greater TGPs on the three new Radeons, despite the fact that it doesn't appear to make a large effect on paper. These improvements are due to the somewhat quicker processor rates and video memory.

According to the reference specifications, the Radeon RX 6950 XT is positioned as the new flagship above the RX 6900 XT and uses a maximum of 335 watts, which is 11% higher than the RX 6900 XT. It is a complement to the portfolio and does not replace the RX 6900 XT, but with a higher-clocked GPU and GDDR6 memory, it should outperform it. The maximum reference power consumption of 250 watts on the RX 6750 XT is also greater than the 230 watts on the RX 6700 XT. In AMD's lineup, these two GPUs will continue to coexist. The RX 6650 XT, on the other hand, entirely replaces the RX 6600 XT. According to AMD, the later card will be phased out altogether once current stocks are depleted.

Improved memory

The three new Radeons have one thing in common: they all have faster GDDR6 memory than the RX 6000 series, which is also the most noticeable change. The new video memory has a speed of 18 Gbit per second, which is somewhat quicker than the current RX 6000 series cards' 16 Gbit per second. With contemporary GPUs, the speed of video memory is a decisive element in performance. With the continued development and improvement of GDDR6, AMD now sees the prospect of marginally improving the performance of its current graphics chips in games without too much intervention. Because these chips use Infinity Cache, the potential improvement is somewhat lesser with the RDNA2 design.

RX 6950 XT and RX 6750 XT: models were tested.

The RX 6950 XT and RX 6750 XT were tested with MSI's Gaming X Trio cards in this review. We were forced to use bespoke cards because AMD refused to offer us reference cards. Furthermore, these two models were unable to be calibrated to the reference standard, potentially distorting the appearance of how much faster the new cards are.

India instructs VPN companies to collect and store data for five and hand over to the government.

 A new governmental order will require virtual private networks to store user data for a minimum of five years.

This is new national directive of the country's IT emergency response team, called.

This is a policy that is probably going to make life harder for VPN businesses and VPN users.

CERT-in announced on Thursday that the VPN companies of the country will have to keep the names of the clients, the physical and IP addresses validated, the habits of use and other forms of personal information.

If the customer cancels their subscription or deletes their account, their information will always be stored in the company's servers according to the directive.

Those who fail to do so could face up to one year in prison under the applicable law cited in the new directive.

The directive does not stop at VPN providers.Data centres and cloud-based providers are listed in the same provision.

India has a long tradition of putting the heavy hand to online activity.

Forcing VPN providers to collect and store critical user data can easily be described by anyone as an attack against users' privacy.

Putting social media platforms under the direct supervision of the government can lead to total censorship of the Internet, as well as a direct attack on users' privacy and freedom of expression online.

Independent researcher Top10VPN estimates that the closures affected 59.1 million users in 2021.

AMD Ryzen 7 5800X3D

 The long-awaited Ryzen 7 5800X3D announced in mid-March and arriving on April 20 is back in the limelight for what, in some ways, we can call the first independent (incomplete) review of the new AMD CPU with 3D V-Cache technology. A user of the Peruvian forum XanxoGaming managed to get his hands on a retail specimen, offering a preview on the performance of this chip several days after the expiry of the official embargo.



We speak of an "incomplete review" as the tests conducted do not include a gaming session, a crucial test bench to understand the real impact of the implementation of the 3D Cache on what is in effect a Ryzen 7 5800X.

As already seen in the benchmarks that emerged from the network in recent days, the absolute performance is not very far from the model currently on the price list , especially in single-core, an area where the new Ryzen 7 5800X3D pays something due to a Boost clock frequency lower than its own. predecessor (4.5 vs 4.7 GHz). The benchmarks (link in SOURCE) are a mixture of synthetics and rendering such as Cinebench and Blender, the latter area where the 64MB of additional 3D cache apparently allows you to still earn from 3% to 11% in multi-core.

Nothing done for the moment, waiting to get our hands on the new AMD CPU and see the first impressions of the media to give a definitive judgment, we just have to wait for further "tips" relating to performance in games. Recall that in this regard AMD has declared a 15% speed increase on Ryzen 9 5900X as well as superior performance to the Intel Core i9-12900K.
