In the present day marks the discharge of Intel’s thirteenth technology Core processor collection, codenamed Raptor Lake. The primary fashions to be unleashed into retail channels are all overclockable components, with six SKUs throughout the Core i9, i7, and i5 product segments. We’ve seen Intel’s heterogeneous or hybrid design with the launch of Intel’s Alder Lake (twelfth Gen Core) merchandise, and the most recent Raptor Lake core brings a really comparable design to the desk, however with refined enhancements designed to assist in giving Intel the vanguard within the desktop market.
The launch of Intel’s new lineup is actually the second half of this fall’s desktop CPU releases. AMD received the primary phrase in a couple of weeks again with the launch of their Ryzen 7000 desktop processors, which launched the Zen 4 structure as effectively a major platform replace for AMD with Socket AM5. The brand new high-end Ryzen chips had been well-received (if a bit costly), setting a brand new bar for efficiency and placing AMD firmly into the lead, at the least for slightly bit. Now it is time for Intel’s personal CPU launch – their rebuttal – the place they get to indicate off what they have been engaged on over the previous few years and whether or not they can retain their edge over AMD for this newest technology of processors.
At a excessive stage, Raptor Lake could be considered a mid-cycle improve of kinds for Intel’s present LGA-1700 platform. As the corporate launched Alder Lake and LGA-1700 only a 12 months in the past, they aren’t seeking to overhaul the core CPU structure fairly so quickly, nor the platform for that matter. Intel is preserving to their two-year platform cycle right here, so the 13th technology of Core processors are designed to deliver extra efficiency to the identical platform as Alder Lake. This makes the Raptor Lake launch considerably extra easy than AMD’s current launch, the place AMD overhauled their whole platform whereas additionally making some extra important CPU structure upgrades within the course of.
As a result of Intel isn’t considerably tweaking their CPU architectures for Raptor Lake, the chip is actually a refined model of Alder Lake. Which means we’re nonetheless a combination of P(erformance) and E(fficiency) CPU cores, primarily based on completely different CPU architectures and designed to permit Intel to hit excessive efficiency ranges in each single/light-threaded workloads that favor the P cores, and closely multi-threaded workloads that may additionally saturate the E cores. The P cores are primarily based on what’s technically a brand new structure, Raptor Cove, whereas the E cores are nonetheless primarily based on the identical Gracemont structure as what we noticed on Alder Lake.
We’ll dive into the inner bits of Raptor Lake a bit afterward, however at a excessive stage, Intel is enhancing efficiency versus Alder Lake in 3 ways.
- Greater clockspeeds, particularly for the P cores, due to some architectural optimization work mixed with additional refinements of the Intel 7 fab course of
- Further E cores in all desktop SKUs, to spice up efficiency in multi-threaded workloads
- Further L2 cache for each the P and E cores. The L3 cache can also be a bit bigger, primarily to accommodate the bigger variety of E cores.
The upper clockspeeds and extra cache imply that Raptor Lake must be sooner in just about all situations in comparison with Alder Lake. For single-threaded and lightly-threaded workloads, the sooner P cores can chew by means of work. In the meantime the complete mixture of further E cores and better clockspeeds implies that multi-threaded efficiency typically exhibits even better features.
Raptor Lake will, in time, be a top-to-bottom launch for Intel and its companions. Which means not solely launching desktop processors, as we’re seeing the primary of at this time, but additionally an entire stack of cell components, with U, P, H, and HX collection processors all deliberate. And whereas cell components are a bit trickier as regards to including clocks and cores whereas staying inside an influence finances, Intel’s design optimizations will also be used to enhance power effectivity as an alternative, which will likely be of better significance for the cell market.
Beginning On the High: Core i9-13900K, i7-13700K, and i5-13600K
However to start out issues off, let’s discuss at this time’s launch. Intel has opted for a top-to-bottom, desktop-to-mobile launch technique, pulling the set off on its overclockable desktop components first. That is typical of Intel’s current desktop launches, and permits them to get their comparatively decrease quantity desktop chips out first whereas persevering with to ramp for greater quantity desktop and cell components. Altogether Intel is launching 3 tiers of chips unfold over 6 SKUs, all overclockable (Okay) and coming both with and with out (F) built-in graphics.
|Intel thirteenth Gen Core, Raptor Lake|
In comparison with the related 12th Gen Core SKUs, Intel has changed the P cores with new Raptor Cove cores on a 1:1 foundation. In the meantime for the E cores, Intel has successfully doubled the variety of E cores for every corresponding SKU. e.g., the Core i5-13600K now has eight E-cores whereas the Core i5-12600K had 4. In any other case, TDPs stay unchanged from the earlier chips, with Intel formally focusing on 125W – although PL2 limits have crept up from 241W to 253W.
Intel Core i9-13900K CPU-Z
Focusing first on the flagship chip, the Core i9-13900K has an unbelievable max P-core turbo of 5.8 GHz. This is a rise of 600 MHz over the Core i9-12900K. Though it has the identical efficiency core depend as its predecessor (although with Raptor Cove cores), it now options double the effectivity cores; a complete of 24 hybrid cores comprised of 8P and 16E cores. This makes for eight extra threads, for a complete of 32, up from 24 on the Core i9-12900K.
One factor to notice in regards to the effectivity cores is that Intel has lowered the bottom frequency of those cores to 2.2 GHz base, which is down from 2.4GHz on Alder Lake. However on the similar time, nonetheless, they’ve additionally elevated the E-core max turbo clockspeed to 4.3 GHz, 400Mhz greater than the three.9 GHz cores on Alder Lake.
Intel has made comparable trade-offs throughout all of its 13th Gen Core SKUs – so this isn’t simply the case for the i9 components, but additionally the i7 and i5 components as effectively. In the end whereas Intel would ideally prefer to run the E cores at their highest clockspeeds always, the expanded variety of cores makes it tougher to remain inside Intel’s official 125W TDP, necessitating a discount on the bottom clockspeeds.
Intel Core i5-13600K CPU-Z
Shifting down the stack, the Core i7-13700K and KF processors each have a complete of sixteen CPU cores (8P+8E), which is up from 8P+4E on the Core i7-12700K. For these components the utmost P-core turbo clockspeed is 5.4 GHz, whereas the P-core base clockspeed stands at 3.4 GHz.
Lastly, filling out the i5 spot in Intel’s lineup is the Core i5-13600K, which we can even be testing at this time. The 13600K components include a complete of fourteen cores in 6P+8E configuration, 4 extra cores than on the Alder Lake i5-12600K. Each the Core i5-13600K and i5-13600KF characteristic a P-core max turbo of as much as 5.1 GHz (up from 4.9 GHz), and an E-core turbo of as much as 3.9 GHz (up from 3.6 GHz).
Z790 Chipset & DDR5-5600 Help
The launch of the 13th Gen Core chips additionally comes with a brand new technology of motherboards from Intel: Z790. As famous earlier, the 13th Gen Core chips are backwards-compatible with 600 collection boards (with the mandatory BIOS replace), to allow them to be used as a drop-in improve or as a part of a recent constructed. However for builders on the lookout for the perfect – and even simply assured CPU compatibility out of the field – Intel is hoping to entice you with Z790.
Like the remainder of the Raptor Lake platform, Z790 will not be a major overhaul of Intel’s present wares. However Z790 does provide perks. Most notable for aspiring builders will likely be that Z790 boards would be the first boards validated for the upper DDR5 reminiscence speeds that Raptor Lake is able to. Whereas Alder Lake formally topped out at DDR5-4800, Raptor Lake can run at DDR5-5600, serving to to feed the beast a bit extra with greater reminiscence clockspeeds. Fanatics will possible run overclocked with XMP kits, however for anybody constructing techniques to spec – be it OEMs or particular person builders – it is a good bump in bandwidth. In the meantime it must be famous that there’s nothing stopping present Z690 boards from being validated for greater speeds as effectively, however that will likely be as much as motherboard producers operating a recent spherical of validation with the brand new Raptor Lake chips.
As for the Z790 chipset itself, it brings a bit extra I/O flexibility in comparison with Z690. Z790 now sports activities 20 PCIe 4 lanes, versus 12 on Z690. That’s augmented with 8 PCIe 3 lanes, 8 fewer than on Z690. Z790 additionally brings assist for another USB 20Gbps (USB 3.2 Gen 2×2) port than its predecessor, making for a complete of 5.
Sizing Up the Competitors: 13th Gen Core vs. Ryzen 7000
With Intel’s shift to a heterogeneous CPU structure, like-for-like comparisons between Intel and AMD have turn into slightly tougher. None the much less, as AMD and Intel have advanced to have similarly-named product stacks – and for that matter comparable pricing – it’s not too onerous to line up what chips are primarily in competitors with one another.

On the high-end, Intel goes up in opposition to AMD’s flagship with fewer P cores (or their AMD equal), however is augmenting that with a a lot bigger variety of E cores. Because of this Intel has extra CPU cores to supply general, however the efficiency implications are very workload dependent. The 13900K shines on duties that may fill all 24 cores/32 threads, and ideally can account for the distinction in efficiency between the core sorts. In any other case, AMD presents fewer complete cores, however extra efficiency on a per-core foundation when 9 to 16 cores are wanted.
In Intel’s favor is a decrease CPU price ($589 vs. $699), in addition to official assist for sooner DDR5 reminiscence (and DDR4, when you want it). Whereas AMD presents extra I/O flexibility with as much as 28 PCIe 5 lanes coming from the CPU, in addition to a bigger general L3 cache.
In the meantime on the different finish of the spectrum, the underside of the stack for the 2 firms is introduced up by the i5-13600K and Ryzen 5 7600X. The Intel chip presents 6 Raptor Cove P cores to AMD’s 6 Zen 4 cores, after which Intel added 8 E cores on prime of that. However on this case Intel not has the value benefit, because the 13600K is $20 dearer than its AMD competitors. This provides Intel a doubtlessly massive benefit in multi-threaded workloads, although for fewer threads, AMD does have a little bit of a clockspeed lead.
