AMD's 3D V-Cache technology utilizes blocks of SRAM stacked on top of the CPU logic die, where CPU cores reside, and allows the processor to access massive pools of cache for applications. However, using this extra level 3 (L3) cache as a RAM disk appears possible, where the L3 SRAM behaves similarly to a storage drive. A big disclaimer here is that this is only possible by exposing the L3 to the CrystalDiskMark benchmark, and no real-world applications can do it in a way that CrystalDiskMark. According to X/Twitter user Nemez (@GPUsAreMagic), the steps to replicate this procedure are: Obtaining an AMD Ryzen CPU with 3D V-Cache, installing OSFMount and creating a FAT32 formatted RAM disk, and running CrystalDiskMark, with values set to values to SEQ 256 KB, Queue Depth 1, Threads 16, and data fill to 0s instead of random.

The results of this experiment? Well, they appear to be rather stunning as the nature of L3 SRAM is that the memory is tiny but very fast and accessible to the CPU, so it can help load data locally before going to the system RAM. With AMD Ryzen 7 5800X3D, the speeds of this RAM disk are over 182 GB/s for reading and over 175 GB/s for writing. In another test, shared by Albert Thomas (@ultrawide219), we managed to see RAM disk based on AMD Ryzen 7800X3D V-Cache, which scores a little less with over 178 GB/s read and over 163 GB/s write speeds. Again, CrystalDiskMark only performed these tests on small allocations varying between 16 MiB and 32 MiB, so no real-world workloads are yet able to utilize this.

AMD's "Zen 3" architecture, particularly in its low-power mobile iterations, change their clock speeds at a very high rate of speed (switching between lower idle clock-speeds to higher boost clock bins), finds a study by Chips and Cheese, which tested 17 processors across brands and machine-architectures, including mobile SoCs. The interesting finding here is that the Ryzen 7 5800U "Zen 3" mobile processor has a much faster speed-ramp than even SoC powering handhelds, such as the Qualcomm Snapdragon 821, returning a ramp-time of just 1.6 ms, compared to 19.6 ms on the Snapdragon. We now see why AMD likes its processors to run detached from the 10 ms tick-rate of Windows internal power-management (the rate at which the OS reports its workload to the processor, so it could respond with a higher performance state). A rapid boost clock ramp rate allows the processor to better ration its power budget in response to workload.

If you are planning to buy a new PC for gaming, MSI MAG META 5 5E is a budget-friendly choice. The MAG META 5 5E is MSI's first full AMD solution gaming desktop. It comes with a Ryzen 7 5800X CPU based on the Zen 3 architecture and AMD Radeon RX 6700 XT that ensures gaming performance thanks to AMD Smart Access Memory Technology. Up to 64 GB of DDR4 RAM can be installed so you will be able to handle gaming and productivity tasks. It comes with up to one M.2 SSD, two 2.5" and two 3.5" slots allowing for utilizing mass storage and faster data access.

As for the thermal solution, the MAG META 5 5E can be configured with an air cooler or liquid cooler. It draws air in from the side and allows plenty of air through the rear and top of the case. There's also additional space for installing fans to bring air through the system. The MAG META 5 5E has RGB strips running along with the front panel and has an interchangeable tempered glass side panel. Users can showcase their style and configuration with an unlimited spectrum of color and dynamic RGB lighting through MSI Mystic Light.

Today, HP Inc. announced its lightest consumer laptop yet, the HP Pavilion Aero 13 Laptop PC. Starting at less than 1 kilogram, the Pavilion Aero 13 delivers a flawless sustainable design with the power to entertain, connect, and be productive. HP also welcomed the HP M24fwa FHD Monitor and HP M27fwa FHD Monitor to the M-Series line of monitors featuring built-in audio; the newest additions are part of the world's first Eyesafe certified monitor series made with recycled ocean bound plastics.

As more people return to a new normal, they need a PC that can move with them while at home and on the go. The PC is used away from home 45% of the time to perform a wide range of tasks, with 25% of time spent streaming videos while 11% of the time is spent being productive, whether it be learning or work-related. With the new Pavilion Aero 13, people can work hard and play hard no matter where they are, on a single, lightweight device.

HP introduced its latest gaming hardware and software designed for today's gamers with the powerful OMEN 16 and OMEN 17, bright and customizable OMEN 25i Gaming Monitor, and community gaming with OMEN OASIS Beta feature in OMEN Gaming Hub. The company also debuted Victus by HP, its next-generation mainstream-level gaming PC portfolio, with a 16-inch laptop.

Gaming continues to be an outlet for entertainment and connecting with friends. Two out of three people are spending more time watching videos and gaming than they did prior to the pandemic, with one in four gaming three to four hours more and almost one in five gaming six to ten hours more a week6. HP's next-generation gaming portfolio is designed for both veteran gamers and enthusiast explorers to be entertained, connected, and empowered to progress in their favorite games.

AMD has quietly launched two new Zen 3 processors for the OEM market with the Ryzen 9 5900 and Ryzen 7 5800. The Ryzen 9 5900 is a 12 core 24 thread processor with a base clock of 3.0 GHz and a max boost clock of 4.7 GHz along with a TDP of 65 W. The clock speeds were lowered due to the 65 W TDP with a base clock is 700 MHz lower than the 5900X while the boost clock is only 100 MHz slower. The Ryzen 7 5800 is an 8 core 16 thread processor with a base clock of 3.4 GHz and a boost clock of 4.6 GHz along with a TDP of 65 W. The base clock is reduced by 400 MHz and the boost clock by 100 MHz compared to the 105 W TDP 5800X. The Ryzen 9 5900 is only ~5% slower than the Ryzen 9 5900X despite a 61.5% lower TDP and reduced clock speeds according to UserBenchmark results. These new processors are now shipping in systems from various integrators such as the Alienware Aurora Ryzen Edition.

AMD appears to be taking baby steps toward expanding its Ryzen 5000 "Zen 3" desktop processor lineup. Dell Canada has started listing a model of the processor series not yet available in the DIY retail channel, the Ryzen 7 5800 (non-X). This isn't a typo, as the option is listed next to the 5800X. The Ryzen 7 5800 is described as being an 8-core part, much like the 5800X, but has a slightly lower max boost frequency of 4.60 GHz, as opposed to 4.70 GHz of the 5800X. It could have a lower nominal (base) frequency compared to the 5800X, and possibly even a lower TDP. The last time AMD released an OEM-exclusive non-X SKU was the Ryzen 9 3900 12-core processor.

AMD's current retail-channel (PIB) lineup of Ryzen 5000 series desktop processors starts at $299 for the 6-core Ryzen 5 5600X, with the company still selling Ryzen 3000-series SKUs such as the 8-core Ryzen 7 3700X under this price. We expect the company to flesh out the 5000-series with SKUs such as the "Ryzen 5 5600 (non-X)," later this year, in response to Intel's 11th Gen Core i5 series based on the "Rocket Lake-S" silicon. Given the fate of the Ryzen 9 3900, we don't expect a broad retail launch of the Ryzen 7 5800.
