With features like fully modular cables with per-wire sleeving, a dynamic hybrid fan control for optimal cooling, and advanced topologies, the Revolution D.F. 12 750W is primed to deliver on both reliability and performance. We will delve into its specifications, build quality, and performance metrics to see if the new unit lives up to Enermax's esteemed legacy.
Cases/Cooling/PSUsSK hynix: GDDR7 Mass Production To Start in Q4'2024 Update 06/13: SK hynix has sent a note to AnandTech clarifying that the company "plans to start mass production of GDDR7 in the fourth quarter of this year when the relevant market opens up." This article has been updated accordingly. Being a major JEDEC memory standard, GDDR7 is slated to be produced by all three of the Big Three memory manufacturers. But it seems that not all three vendors will be kicking off mass production at the same time. SK hynix was at this year's Computex trade show, showing off their full lineup of memory technologies – including, of course, GDDR7. SK hynix is the last of the major memory vendor's we've seen promoting their memory, and fittingly, they seem to be the last in terms of their mass production schedule. According to company representatives, the firm will kick off mass production of their GDDR7 chips in the last quarter of 2024. Comparatively, the company's cross-town rival, Samsung, is already sampling memory with the goal of getting it out the door in 2024. And Micron has been rather gung ho about not only starting mass production this year, but starting it early enough that at least some of their customers will be able to ship finished products this year. That said, it bears mentioning that with industry-standard memory technologies, mass production at one vendor does not indicate that another is late; it is just indicating that someone was first to validate with a partner and that partner plans to ship its product in 2024. And while mass production remains another 4+ months out, SK hynix does have sample chips for its partners to test right now, and the chips have been demonstrated at Computex. As far as SK hynix's floor booth at Computex 2024 is concerned, the company had GDDR7 chips on display along with a table essentially summarizing the company's roadmap. For now, SK hynix is planning on both 16Gbit and 24Gbit chips, with data transfer rates of up to 40 GT/s. Though when SK hynix intends to launch their higher-end configurations remains to be seen. Both of the company's rivals are starting out with 16Gbit chips running at 32 GT/sec, so being the first to get a faster/larger chip out would be a feather in SK hynix's cap. GPUs
Realtek Outlines SSD Controller Roadmap: High-End PCIe 5.0 x4 Platform in the Works While Realtek is best known in the enthusiast space for for its peripheral controllers such as audio codecs and network controllers, the company also has a small-but-respectable SSD controller business that tends to fly under the radar due to its focus on entry-level and mainstream drives. But Realtek's stature in the SSD space is on the rise, as the company is not only planning new PCIe Gen5 SSD controllers, but also their first high-end, DRAM-equipped SSD controller. For this year's Computex trade show, Realtek laid out a new SSD controller roadmap that calls for the company to release a trio of new SSD controllers over the next couple of years. First up is a new four-channel entry-level PCIe 4.0 controller, the RTS5776DL, which will be joined a bit later by a PCIe 5.0 variant, the RTS5781DL. But most interesting on Realtek's new roadmap is the final chip being planned: the eight-channel, DRAM-equipped RTS5782, which would be the company's first high-end SSD controller, capable of hitting sequential read rates as high as 14GB/second.

G.Skill on Tuesday introduced its ultra-low-latency DDR5-6400 memory modules that feature a CAS latency of 30 clocks, which appears to be the industry's most aggressive timings yet for DDR5-6400 sticks. The modules will be available for both AMD and Intel CPU-based systems.
With every new generation of DDR memory comes an increase in data transfer rates and an extension of relative latencies. While for the vast majority of applications, the increased bandwidth offsets the performance impact of higher timings, there are applications that favor low latencies. However, shrinking latencies is sometimes harder than increasing data transfer rates, which is why low-latency modules are rare.
Nonetheless, G.Skill has apparently managed to cherry-pick enough DDR5 memory chips and build appropriate printed circuit boards to produce DDR5-6400 modules with CL30 timings, which are substantially lower than the CL46 timings recommended by JEDEC for this speed bin. This means that while JEDEC-standard modules have an absolute latency of 14.375 ns, G.Skill's modules can boast a latency of just 9.375 ns – an approximately 35% decrease.
G.Skill's DDR5-6400 CL30 39-39-102 modules have a capacity of 16 GB and will be available in 32 GB dual-channel kits, though the company does not disclose voltages, which are likely considerably higher than those standardized by JEDEC.
The company plans to make its DDR5-6400 modules available both for AMD systems with EXPO profiles (Trident Z5 Neo RGB and Trident Z5 Royal Neo) and for Intel-powered PCs with XMP 3.0 profiles (Trident Z5 RGB and Trident Z5 Royal). For AMD AM5 systems that have a practical limitation of 6000 MT/s – 6400 MT/s for DDR5 memory (as this is roughly as fast as AMD's Infinity Fabric can operate at with a 1:1 ratio), the new modules will be particularly beneficial for AMD's Ryzen 7000 and Ryzen 9000-series processors.
G.Skill notes that since its modules are non-standard, they will not work with all systems but will operate on high-end motherboards with properly cooled CPUs.
The new ultra-low-latency memory kits will be available worldwide from G.Skill's partners starting in late August 2024. The company did not disclose the pricing of these modules, but since we are talking about premium products that boast unique specifications, they are likely to be priced accordingly.

MemoryIt is with great sadness that I find myself penning the hardest news post I’ve ever needed to write here at AnandTech. After over 27 years of covering the wide – and wild – world of computing hardware, today is AnandTech’s final day of publication.
For better or worse, we’ve reached the end of a long journey – one that started with a review of an AMD processor, and has ended with the review of an AMD processor. It’s fittingly poetic, but it is also a testament to the fact that we’ve spent the last 27 years doing what we love, covering the chips that are the lifeblood of the computing industry.
A lot of things have changed in the last quarter-century – in 1997 NVIDIA had yet to even coin the term “GPU” – and we’ve been fortunate to watch the world of hardware continue to evolve over the time period. We’ve gone from boxy desktop computers and laptops that today we’d charitably classify as portable desktops, to pocket computers where even the cheapest budget device puts the fastest PC of 1997 to shame.
The years have also brought some monumental changes to the world of publishing. AnandTech was hardly the first hardware enthusiast website, nor will we be the last. But we were fortunate to thrive in the past couple of decades, when so many of our peers did not, thanks to a combination of hard work, strategic investments in people and products, even more hard work, and the support of our many friends, colleagues, and readers.
Still, few things last forever, and the market for written tech journalism is not what it once was – nor will it ever be again. So, the time has come for AnandTech to wrap up its work, and let the next generation of tech journalists take their place within the zeitgeist.
It has been my immense privilege to write for AnandTech for the past 19 years – and to manage it as its editor-in-chief for the past decade. And while I carry more than a bit of remorse in being AnandTech’s final boss, I can at least take pride in everything we’ve accomplished over the years, whether it’s lauding some legendary products, writing technology primers that still remain relevant today, or watching new stars rise in expected places. There is still more that I had wanted AnandTech to do, but after 21,500 articles, this was a good start.
And while the AnandTech staff is riding off into the sunset, I am happy to report that the site itself won’t be going anywhere for a while. Our publisher, Future PLC, will be keeping the AnandTech website and its many articles live indefinitely. So that all of the content we’ve created over the years remains accessible and citable. Even without new articles to add to the collection, I expect that many of the things we’ve written over the past couple of decades will remain relevant for years to come – and remain accessible just as long.
The AnandTech Forums will also continue to be operated by Future’s community team and our dedicated troop of moderators. With forum threads going back to 1999 (and some active members just as long), the forums have a history almost as long and as storied as AnandTech itself (wounded monitor children, anyone?). So even when AnandTech is no longer publishing articles, we’ll still have a place for everyone to talk about the latest in technology – and have those discussions last longer than 48 hours.
Finally, for everyone who still needs their technical writing fix, our formidable opposition of the last 27 years and fellow Future brand, Tom’s Hardware, is continuing to cover the world of technology. There are a couple of familiar AnandTech faces already over there providing their accumulated expertise, and the site will continue doing its best to provide a written take on technology news.
As I look back on everything AnandTech has accomplished over the past 27 years, there are more than a few people, groups, and companies that I would like to thank on behalf of both myself and AnandTech as a whole.
First and foremost, I cannot thank enough all the editors who have worked for AnandTech over the years. T... Site Updates
