I swear to God it's too warm to do anything in the UK this week. I am barely coping in the heat if it wasn't for the array of small Ohyama Woozoo fans I have, plus an array of Meaco air circulators and more besides. Of course this week is the week that all the deals are happening - that's just the way of the world it seems - and none of us can catch a naffing break. Godspeed to anyone outside doing real work in this UK heat - can we make air con mandatory in new homes, please?

Being too hot to do anything means it's too warm to build your own PC as I see it, so to save you the hassle, I've gone on my merry way and found an array of six pre-built PC deals from up and down the price ladder across the UK and USA that should give you plenty of grunt for your favourite games. Finding discounts on pre-built PCs was surprisingly difficult, owing to the issues we've seem with everything from shortages for components to pesky overpricing that doesn't do anybody any favours, meaning that the whole pricing structure for certain tiers of PC have shifted up somewhat, which doesn't help anybody.

The six PCs I've put below have been picked out in the following order. First based on region, and then in order of mid-range, budget and then expensive - putting the one that I think is best for price to performance first and hitting a strong mid-tier choice with good power, then a more affordable choice for 1080p or 1440p gaming, and then a bit of a splurge option if you've got the spare cash to play at 4K. Given the way things are these days, I haven't gone mad with the latter choice and specced out a money-no-object choice, and kept to things that are a bit more reasonable given the circumstances for at least a hint of affordability.

Of course, we're sticking with the fact this is anti Prime Day coverage after all, so none of these deals are from The Retailer Who Must Not Be Named, instead from either PC builders directly or larger retailers with surpisingly good deals given the current context. If you're on the lookout for more deals after this, then you can check out James' master guide for our RPS Anti Prime Day deals coverage, or my roundup of seven more excellent deals across the UK and USA. Without further ado, here are six prebuilt PC deals I've spotted from other retailers that I think are worth your time.

Consumer AMD CPUs will once again offer encryption protections against physical attacks after facing user backlash for silently removing the feature.

As Ars reported last week, AMD stripped the protection, known as TSME, from consumer Ryzen processors. Short for Transparent Secure Memory Encryption, TSME encrypts the entire contents stored in memory, making the data useless to adversaries performing cold boot attacks and similar intrusions requiring physical access.

Now you see it, now you don't, soon you'll see it again

About a decade ago, AMD added TSME to its high-end CPUs. Over the next few years, AMD added the protection to lower-end processors, including the consumer version of its Ryzen chips, a CPU that costs less than the Pro version. Over the years, users of these lower-end chips have gotten used to the added security, although some security experts (and plenty of novices, too) note that consumer chips are far less likely to be targeted by physical attacks. Recently and without warning or notice, the lower-end line of AMD chips suddenly dropped the protection, and it did so in a way that was impossible to detect on Windows machines and required a fair amount of technical work when using Linux. AMD last week declined to explain or acknowledge the change.

Over time, AMD added TSME to lower-end processors, including the consumer version of its Ryzen chips, a CPU that costs less than the Pro version.

Now you see it, now you don't

AMD has yet to say why TSME worked on these CPUs, or even to confirm the change. AMD declined to answer questions sent by email other than to say TSME "is a security feature only applied to PRO CPUs as part of AMD PRO Technologies." The statement is the first known time the chipmaker has explicitly made this restriction public.

At some point during the fog of 2021 or 2022, I noticed that my son's preferred brand of fruit snacks had switched from including 0.9 ounces per pouch to 0.8 ounces per pouch. Most shrinkflation is meant to fly under the radar, but in this case, I just happened to notice it. It felt bad! It's tangible evidence that your money is not going as far as it did in the very recent past.

A little over a year ago, AMD launched the Radeon RX 9070 for a suggested retail price of $549. This month, it's launching the similarly named Radeon RX 9070 GRE for a suggested retail price of $549. This new card (actually the US launch of a GPU that's been available in China for a year or so) has 85 percent as many GPU cores, 75 percent as much memory, and 66 percent as much memory bandwidth as the regular RX 9070.

We'll evaluate the RX 9070 GRE in the context of the current GPU market, where prices have been edging upward due to the same AI-driven RAM shortages and price hikes that have made PC building and buying such a miserable experience for the last few months. But it's hard not to be a little upset about such a clear example of GPU shrinkflation—the same money for a markedly inferior product.

One of the benefits of building an AMD PC is that the company has historically supported its processor sockets for longer than Intel does, allowing the same motherboard (and RAM kit, if you want) to power your PC through multiple CPU upgrades. Today at Computex, AMD announced chips for the current AM5 socket and the improbably-still-around AM4 socket that will help extend their lives a little further, a nod to just how expensive it has become to build a new PC or perform a major upgrade these days.

The first of these announcements is something we knew about already: the relaunch of 2022's Ryzen 7 5800X3D, the first of AMD's commercially available 3D V-Cache processors. Dubbed a "10th Anniversary Edition" in reference to how long Socket AM4 has been around, the re-released chip is slower than regular 8-core Ryzen 5000-series CPUs in general productivity tasks but comes with 64MB of extra L3 cache that disproportionately benefits games. If you're trying to use a high-end GPU with an AM4 motherboard, it could help keep your CPU from being a performance bottleneck. The 5800X3D (re-)releases on June 25 for a suggested retail price of $349, which is less than it currently costs to buy secondhand.

As for the current AM5 socket, AMD officially announced that it was extending its support to at least 2029—it was originally planned to last until 2025, then until "2027+," so that means between two and four years of additional support, depending on how you're counting.

Intel plans to ship an AI chip by the end of this year that uses cheaper memory and cooling technology than rival offerings from Nvidia and AMD, as the US chipmaker seeks to capitalize on a sharp turnaround in its fortunes.

Kevork Kechichian, who leads Intel’s data center group, told the FT that the company is “starting with the basics” as it tries to challenge its rivals in the booming market for semiconductors that power AI.

Its new “Crescent Island” graphics processing unit is designed to speed up “inference” tasks, the stage when a user makes their request, rather than the training of models, an area where Nvidia’s processors are dominant.

When AMD announced version 4 of its FidelityFX Super Resolution (FSR) graphics upscaling technology early last year, it came with strings attached: The improved hardware-backed image quality would be available only on Radeon RX 9000-series GPUs based on the RDNA4 architecture, not on any older Radeon GPUs.

To date, AMD has released only a handful of 90-series graphics cards, including the RX 9070 XT, the RX 9070, the 8GB and 16GB versions of the RX 9060 XT, and an RX 9060 that's only available to PC companies rather than end users. That list notably doesn't include any integrated GPUs, such as those found in AMD-powered thin-and-light laptops or gaming handhelds like the Steam Deck and its imitators.

Over a year later, AMD Computing and Graphics SVP Jack Huynh has announced that a version of FSR 4 is finally coming to older GPUs. The rollout will begin in July with RDNA3- and 3.5-based GPUs, which include the Radeon RX 7000 series, as well as integrated GPUs like the Radeon 890M and Radeon 8060S.

Last year, we noted how the long-standing vagaries of HDMI licensing and open source AMD driver development combined to prevent the upcoming Steam Machine from receiving official support for the HDMI 2.1 display standard. Now, though, it seems that AMD is making real progress on adding full HDMI 2.1 compliance to its Linux amdgpu driver in the near future.

In patch series notes for an amdgpu driver update posted on Friday (and noticed by Phoronix), AMD's Harry Wentland says that the company is finally adding HDMI FRL (Fixed Rate Link) support to the popular Linux display driver. That's the feature that allows for higher bandwidth on compatible HDMI cables compared to the TMDS standard found on HDMI 2.0 and earlier. That in turn enables direct support for higher resolutions, dynamic HDR, and features like Variable Refresh Rate that aren't supported in HDMI 2.0.

Wentland notes that this update is still just "a representative subset of HDMI compliance," in part because it is missing the code to support the Display Stream Compression (DSC) that allows for even higher resolutions and frame rates up to 10K at 100 Hz. But Wentland adds that DSC support "is still being tested and will be sent out later," and that "a full compliance run" for HDMI 2.1 is "in the works." An AMD driver developer with the handle agd5f also commented on Phoronix, noting that "a full implementation [of HDMI 2.1] will ultimately be available once the patches are ready and have completed compliance testing."
