Whereas Alder Lake set the course for Intel’s near-term processor designs, Raptor Lake optimized it. Intel had improved upon Alder Lake’s “Golden Cove” and “Gracemont” microarchitectures with Intel 7, Intel’s third era 10nm “SuperFin” course of, relying closely on the effectivity positive aspects of the refined node. Describing the effectivity in broad strokes, Intel mentioned that Raptor Lake provides comparable efficiency to Alder Lake at half or perhaps a quarter of the facility.

The most impactful improve is within the core rely. All SKUs from the efficiency to the midrange now carry extra cores and have elevated clock speeds.

At the highest of the stack is the Core i9-13900K/KF. With 24 cores break up between eight efficiency cores (P-cores) and 16 effectivity cores (E-cores), they’ve eight extra E-cores than the Core i9-12900K. Because the “Gracemont” E-cores don’t help hyperthreading, the Core i9-13900K carries a complete of 32 threads. Intel mentioned that the Core i9-13900K can attain 5.8GHz out of the field, a 600MHz improve over the Core i9-12900K regardless of having double the variety of E-cores.

Moving down the stack, the Core i7-13700KF additionally acquired 4 extra E-cores, bumping its core rely to 16. At 5.4GHz, its P-core peak frequency is 400MHz increased than the Core i7-12700K. The Core i5-2600K/KF comply with the identical development: 4 extra E-cores and a better clock velocity.

Intel’s efficiency claims

Intel says that Raptor lake delivers 15 per cent higher single-thread efficiency and 41 per cent increased multithreaded efficiency. In single-threaded workloads, the frequency increase accounts for a lot of the efficiency improve, aided by an enhanced cache structure and reminiscence enhancements. The further E-cores performed the largest half in rising multithreaded efficiency, as anticipated.

What this implies is a 58 per cent uptick in gaming efficiency over the AMD Ryzen 9 5950X, Intel claimed. On the gaming efficiency graph under, utilizing a refined purple line, Intel additionally indicated the efficiency of the Ryzen 7 5800X3D, a gaming-oriented AMD processor that featured a excessive clock velocity and a whopping 96MB of 3D V-Cache. Against it, the Core i9-13900K seems to commerce blows.

Intel additionally claims that the Core i9-13900Kleads in artistic workloads by demonstrating that the chip holds as much as a 69 per cent lead over the Ryzen 9 5950X.

To obtain this, Intel not solely needed to depend on its new course of but in addition needed to do some tweaking to the microarchitecture.

Prefetching, the operate to predictively load data into cache reminiscence earlier than it’s wanted, has been polished on each the P-cores and E-cores. Intel says that through the use of machine studying and real-time telemetry information, prefetch can dynamically regulate based mostly on the workload sort. The firm claims that the brand new system will increase efficiency by 4 per cent in purposes just like the Adobe suite. And though the E-core’s structure remained the identical gen-on-gen, the prefetch enchancment will increase its multithreaded efficiency by seven per cent.

The ring, or the on-die interconnect, is now additionally “dramatically faster” at 5GHz—900MHz increased throughout all core turbo than Alder Lake. Intel says the lowers latency path to reminiscence is “critical” to recreation efficiency and brings round 5 per cent body charges on common.

Lastly, Raptor Lake encompasses a tweaked Thread Director that may higher classify threads. It may also higher distinguish between user-initiated and background duties. This new characteristic apparently requires the Windows 11 H2 replace that was launched final week.

Increased energy limits

Increasing clock speeds and core rely naturally will increase energy consumption, however it didn’t appear to influence the fanatic vary all that a lot. Although the Core i9-13900K has extra cores and a better increase frequency, its turbo energy restrict solely elevated by 10W over the Core i9-12900K, now demanding 253W in comparison with 241W. To hold it cool, air cooling is completely out of the query; a big all-in-one liquid cooler is virtually obligatory.

The efficiency Core i7 phase, nonetheless, is a distinct story. The Core i7-13700K now additionally limits turbo energy at 253W, which is 63W increased than the Core i7-12700K. That further energy feeds the 4 further E-cores, and helps to lift the turbo frequency on each the E-core and P-core from 5.0GHz/3.8GHz on the earlier era to five.4GHz/4.2GHz. This must be no less than a bit regarding as it might demand a way more succesful cooler than the earlier era.

The Core i5s asks for extra energy too, albeit lower than the Core i7 collection. The Core i5-13600K has a max turbo energy of 181W, a 31W improve over the Core i5-12600K. Its turbo frequencies (P-Core/E-core) have been set at 5.1GHz/3.9GHz. For comparability, the Core i5-12600K featured a P-Core/E-core frequency of 4.9GHz/3.6GHz.

Chipset and platform enhancements

A brand new chip means a brand new chipset. Raptor Lake shall be paired with the Z700 motherboards, however they aren’t a compulsory purchase for house owners of a Z600 motherboard.

Raptor Lake continues to make use of the identical LGA1700 socket as Alder Lake and is backward appropriate with Z600 motherboards. This implies that customers gained’t must buy new motherboards and reminiscence in the event that they’re seeking to improve from the earlier era. However, they could must put money into a greater cooler in the event that they’re leaping between tiers or grabbing the brand new i7s.

The Z700 chipset brings eight further PCIe Gen 4.0 lanes for a most of 20. In addition, it additionally helps eight PCIe gen 3.0 lanes for a complete of 28 lanes off of the motherboard. Communication between the motherboard and chipset is delivered over DMI 4.0, which was launched within the final era.

DDR5 reminiscence now performs higher with Intel’s processors. Not solely does Raptor Lake’s DDR5 reminiscence spec has been raised to 5600MHz (800MHz increased than Alder Lake), however Intel additionally guarantees that its excessive reminiscence profiles (XMP) can now hit 6,600MHz and past frequencies. As with Alder Lake, the Z700 collection platforms will proceed to help each DDR4 and DDR5 reminiscence.

In addition to reminiscence enhancements, the Raptor Lake platform will even convey nifty options like Wi-Fi sensing, and Bluetooth LE audio.


Good news: all Raptor Lake processors introduced to this point have the identical MSRP because the earlier era. At these costs, Intel is significantly dialling up the worth proposition in opposition to AMD’s just lately introduced Ryzen 7000 collection processors, particularly now that they’ve much more cores than earlier than.

Comparing the launch costs, the Core i9-13900K sits between the 16-core Ryzen 9 7950X and the 12-core Ryzen 9 7900X, undercutting the previous by $110, and is $40 greater than the latter. Doing some finger math, $40 involves round 7 per cent of $549 (the retail value of the Ryzen 9 7900X). If the Core i9-13900K can beat the Ryzen 9 7900X by simply 7 per cent in each single and multithreaded purposes, then it’s simply the higher purchase. Although AMD extolled the advantages of its Zen 4 microarchitecture, we’re nonetheless anticipating the Core i9-13900K to be aggressive in opposition to the dearer Ryzen 9 7950X.

Still, the truth that the Ryzen chips solely have fully-fledged efficiency cores can’t be ignored. The Ryzen 9 7950X has 16 of them, whereas the Ryzen 9 7900X has 12. In distinction, the Core i9-13900K has simply eight P-cores. In workloads that use fewer than 16 cores, the Ryzen chips might nonetheless come out on high.

The Core i7-13700K and Core i7-13700KF hover across the $399 MSRP of the 8-core Ryzen 7 7700X. Again, wanting on the spec sheet alone, the AMD chip might discover it troublesome to maintain tempo in multithreaded workloads, given the hole in core rely.

Similarly, the Core i5-13600K and Core i5-13600KF costs flank that of the $299 Ryzen 5 7600X. Like the i7s, they match the AMD chip core-for-core in P-cores but in addition have eight E-cores. It as soon as once more implies increased multithreaded efficiency.

With that mentioned, AMD’s Ryzen 7000 processors do seem to have decrease thermal design energy. The Ryzen 5 7600X additionally has a better increase frequency than the Core i5-13600K, which might assist its efficiency.

Raptor Lake and the Intel Z790 chipset shall be accessible beginning Oct. 20, 2022.
