Intel has decided to discontinue its entire 13th Gen Raptor Lake lineup of overclockable "K-series" CPU SKUs. According to an official product change notice, the company will stop accepting orders for chips like the Core i9-13900KS, Core i9-13900K, Core i9-13900KF, Core i7-13700K, Core i7-13700KF, Core i5-13600K, and Core i5-13600KF after May 24th, 2024. Final shipments to vendors are targeted for June 28th. After those dates, availability of the unlocked Raptor Lake processors will rapidly diminish as the remaining inventory gets sold off, possibly at inflated prices due to shortages. This discontinuation comes just over a year after Raptor Lake's launch in late 2022, which delivered additional performance improvements over the previous Alder Lake generation.

Raptor Lake brought higher clocks, more cache, additional efficiency cores, and enough muscle to compete with AMD's Ryzen 7000 CPUs in many workloads. Interestingly, Intel has not yet discontinued Alder Lake, suggesting those 12th-generation chips may still be available for some time. While the death of the overclockable Raptor Lake K-series CPUs is unfortunate for enthusiasts, there is an upside—it paves the way for Intel's current generation Raptor Lake refresh, 14th generation Core processors, to clear inventory before the next-generation processors arrive. The 15th generation "Arrow Lake" Core Ultra 2 series of processors could be teased at the upcoming Computex event in June.

Intel tends to send out elaborate media kits with their pre-launch processor review samples. One such kit landed with Caseking, which posted a reveal of what it could look like. A large cardboard box roughly the size of an ATX motherboard box shimmers with holographic film on all its sides. You open its lid to reveal a giant picture of a "Raptor Lake-S" (8P+16E) die. In real life, this die is roughly 260 mm² in area (about that of a postage stamp). The bottom end of this "die" opens out in two segments, one reveals an acrylic memento with another enlarged "Raptor Lake" die, which you can hang on a wall or as a backdrop in your streams; while the other half reveals two paperboard jewel-cases, one contains the Core i9-13900K (8P+16E), and the other a Core i5-13600K (6P+8E). Fancy media kits aren't new, and most hardware companies send them with their major product releases, so sites can optionally do an unboxing preview at a date before that of the review. You can watch Caseking's unboxing video from the source link below.

Intel today launched its 13th Gen Core "Raptor Lake" desktop processors, and companion 700-series motherboard chipset. These processors are built in the same LGA1700 package as the previous generation "Alder Lake," and are backwards-compatible with 600-series chipset motherboards through a BIOS update. Likewise, 700-series chipset motherboards support older "Alder Lake" processors. With the new 13th Gen Core, Intel is broadly promising an up to 15% uplift in single-threaded performance, which has a bigger bearing on gaming performance; and an up to 41% multi-threaded performance uplift; over the previous-generation, when comparing the top Core i9-13900K with its predecessor, the i9-12900K. Intel also claims to have outclassed the AMD Ryzen 9 5950X in multi-threaded performance, and the Ryzen 7 5800X3D in gaming performance.

Intel's performance claims are backed by some impressive hardware changes despite the company sticking with the same Intel 7 (10 nm Enhanced SuperFin) foundry node as "Alder Lake." To begin with, the single-thread performance uplift comes from the new "Raptor Cove" performance-core, which promises an IPC uplift over the previous-generation "Golden Cove," comes with more dedicated L2 cache of 2 MB per core (compared to 1.25 MB per core in the previous-generation); and significantly higher clock-speeds, going all the way up to 5.80 GHz. "Raptor Lake" has up to 8 P-cores, but the company has put in a lot of work in improving the contribution of E-cores to the processor's overall multi-threaded performance uplift. This is achieved by doubling the E-core count to 16. These are the same "Gracemont" E-cores as previous-generation, but Intel has doubled the L2 cache that's shared in a 4-core Gracemont cluster, from 2 MB per cluster to 4 MB. There are upgrades to even the hardware prefetchers of these cores.

There have been some rumours circulating about Intel looking at increasing the pricing for its CPUs and if a screenshot from Amazon UK posted by @momomo_us on Twitter is to be believed, it looks like it'll be a significant increase in price. The Core i9-13900KF is listed with a price of £750.12, or almost US$815, admittedly including 20 percent VAT. That's a significant price increase over the Core i9-12900KF which normally retails for £679, but is currently offered for £608.99 by Amazon UK. It doesn't look better further down the stack either, with the Core i7-13700K coming in at £547.22 compared to a retail price of £409.88 for the Core i7-12700K.

The Core i7-13700KF should land at £516.58, versus £396.40 for the Core i7-12700KF. Finally the Core i5-13600KF ends up at £349.75 versus £272.99 for the Core i5-12600KF. As such, we're looking at a price increase of somewhere between around £80 and £140 depending on the SKU. These are not insignificant price increases if these are the actual retail prices we can expect when Intel launches its 13th gen Core processors in October. Hopefully we'll get some clarity next week, when Intel is said to be announcing the new CPUs. @momomo_us also provided some box art for the new processor boxes, for your viewing pleasure.

Is there anything better than yet another benchmark leak of upcoming products? This time around we don't have to make do with Geekbench or some other useless benchmark, as a bilibili user in the PRC has posted a video where he has put the upcoming Intel Core i5-13600K and Core i7-13700K CPUs through 10 different games, plus 3DMark Fire Strike and Time Spy. This has been done at 1080p, 1440p and 2160p at that, using a GeForce RTX 3090 Ti graphics card. Both CPUs are QS or Qualification Samples, which means they're going to be close to identical to retail chips, unless there are some last minute issues that are discovered. The CPUs were tested using an ASRock Z690 Steel Legends WiFi 6E motherboard, well, two actually, as both a DDR4 and a DDR5 version were used. The DDR4 RAM was running at 3600 MHz with slow-ish timings of 18-22-22 in gear 1, whereas the DDR5 memory was running at 5200 MHz, most likely at 40-40-40 timings, although the modules were rated for 6400 MHz, in both cases we're looking at 32 GB.

Courtesy of @harukaze5719, we have some much easier to read graphs than those provided by the person that tested the two CPUs, but we've included the full graphs below as well. Each CPU was compared to its current SKU equivalent from Intel and in many of the games tested, the gain was a mere percent or less to three or four percent. However, in some games—at specific resolutions—especially when paired with DDR5 memory, the performance gain was as much as 15-20 percent. A few of the games tested, such as FarCry 6 at 4K, the game ends up being GPU limited, so a faster CPU doesn't help here as you'll see in the graphs below. There are some odd results as well, where the DDR5 equipped systems saw a regression in performance, so it's hard to draw any final conclusions from this test. That said, both CPUs should offer a decent performance gain, as long as the game in question isn't GPU limited, of around five percent at 1440p when paired with DDR5 memory.

It's a busy day when it comes to Intel Raptor Lake benchmark leaks and this time around, we're looking at a pair of Core i5-13600K CPUs, but in two different motherboards. The first CPU sits in an ASUS ROG Maximus Z690 Extreme board and is paired with 32 GB of DDR5 memory, whereas the second CPU is in an ASRock Z690 Steel Legend WiFi 6E board, this one also paired with 32 GB of RAM, but DDR4 rather than DDR5. Both systems are running Windows 10 and unlike the Core i9-13900K results that we saw a couple of weeks ago, these two results are both valid according to the Geekbench results browser.

Courtesy of @harukaze5719 we have a nice graph with the results below, even comparing them to the average Geekbench results for a Core i5-12600K, as well as a Ryzen 9 5950X and a Ryzen 5 5600X. The Core i5-13600K beats everything in the single threaded results and the ASUS system is not far behind the Ryzen 9 5950X in the multithreaded tests. The ASUS system is significantly faster than the ASRock one though, so it seems like Raptor Lake is really making the most out of DDR5 memory. As we don't know the memory clocks, it's hard to say if that is also a contributing factor here, but it's likely that the ASUS system uses much faster memory, as in some of the sub-tests like Rigid Body Physics, the two systems are on par in terms of performance. It'll be interesting to see how Intel prices these upcoming CPUs, especially considering that the company has already warned it'll raise its prices in time for the retail availability of Raptor Lake.
