Intel Core i9-13900K and i5-13600K Review: Raptor Lake Brings More Bite
by Gavin Bonshor on October 20, 2022 9:00 AM ESTZ790 Chipset: More I/O Than Z690, But Same Performance
One of the main talking points surrounding all processor launches at present is platform affordability. When Intel launched its 12th Gen Alder Lake core series processors towards the tail end of 2021, it enabled users to utilize the higher bandwidth DDR5 memory in a desktop platform. As DDR5 memory supply was low and consumer demand was high during Alder Lake’s initial launch, this sky rocketed prices and it made it near impossible for users to buy a DDR5 kit to use with 12th Gen. Intel did offer support for both DDR5-4800 and DDR4-3200, but motherboards (600-series) could only support one or the other.
Although this hasn’t changed with Intel’s latest Z790 chipset, Intel does offer support for both DDR5 and DDR4 with its 13th Gen Raptor Lake Core processors; something AMD doesn’t do with Ryzen 7000 series, much to consumer’s angst. Even though Intel has opted for a higher DDR5 memory speed (5600 MT/s versus 4800 MT/s) compared to Alder Lake, DDR4 memory support remains at DDR4-3200.

Looking at the Intel chipset comparison table above, one could really question what’s actually different about Z790 when compared directly to Z690, especially given that Z690 does allow full support for 13th Gen processors; yes, there is no hidden secret sauce or performance unlocking features, Z690 and Z790 will perform the same in compute and gaming.
The key differences are that Z790 offers an additional 8 x PCIe 4.0 lanes from the chipset, but at the cost of 8 x PCIe 3.0 lanes. This means Z790 still offers a total of 28 x PCI lanes when compared to Z690, but it gives vendors further flexibility to utilize the extra PCIe 4.0 lanes for high bandwidth M.2 slots and additional Thunderbolt 4 controllers, while still offering a few PCIe 3.0 lanes for devices such as additional NICs, streaming cards, and other non-bandwidth critical devices.
Intel says Goodbye to Optane Memory (Cache), No Support on Z790
One thing to note with Z790 is that along with Intel’s decision to kill its Optane business; this chipset will NOT support Intel's Optane Memory, Intel's Optane-based drive caching solution. Using Z690 combined with 12th Gen should still yield the same level of support as before, but using Z790 will not allow Optane Memory to be used, which is understandable as Intel winds down its Optane and 3DXpoint storage division.
The main benefit for opting for Z790 over Z690 is essentially down to PCIe 4.0 I/O capabilities, with support for one more additional USB 3.2 G2x2 Type-C port compared to Z690. Having spoken to Intel directly about processor performance with either chipset, they made it clear that they do not expect compute or gaming performance to be any different regardless of whether you’re using the new Z790 or the existing Z690 chipset.

Raptor ask first day in the open market;13900K = $845 + 43% over i$1K
13900KF = $1187 + 110%
13700K = $393 (-12.5%) some assemblance of reality in the world
13700KF = $415 + 8%
13600K = $393 + 23%
13600KF = $415 + 34%
Raphael R7K fifth week of supply open market;
7950X = $933 + 33.6%
7900X = $695 + 26.6%
7700K = $477 + 19.5%
7600X = $422 + 41.3%
In July Intel signaled a +20% price increase and AMD ignored Intel counsel and the channel will settle that question by Black Friday Cybor Monday. The question has already been answered for dGPU in the market for RTX 4090?

That's why I usually buy new hardware a bit after Xmas. That wouldn't have worked for several reasons in 2020-21, but other years it's served me well. ReplyBruzzone - Friday, October 21, 2022 - link
Prior gen CPU and dGPU production overage run end absolutely a "bit after Christmas".New primary dGPU a Pareto distribution curve and that does not explain it the situation assessment fully for all consideration.
On new CPU production AMD ignoring Intel + 20% price increase offer it's a CPU new primary price war unless the channel disagrees bringing normalcy to cost : price / margin assessment on cost : price / margin realities.

Like any other CPU launch, the only prices we have at the start are the prices provided by the manufacturers. Retail prices can and will vary, especially at the very start when chips are in short supply.It's best to consider it guidance rather than hard numbers. Reply

Now this is what we want to see! Proper, vicious, dog-eat-dog competition from Intel and AMD. I've rarely seen a clearer example of why competition is good and entrenched monopolies (or near monopolies) are bad. Hats off to both competitors. ReplyOxford Guy - Friday, October 28, 2022 - link
Duopoly is hardly adequate competition. ReplySilver5urfer - Thursday, October 20, 2022 - link
I will keep it short.Buy Intel get it under AIO and get ready for 340W load on 13900K while AMD Zen 4 is at 95C but its significantly lower power at 230W only max. The flagship parts need AIOs no Air coolers, but with AMD some of the Air coolers can work without problem since the heat is only factor but not the high power as the Temp target can be set on AMD platform from 95C to 92C. Intel 12900K and up aka 13700K, 13900K cannot be tamed on Air coolers esp when you tune them. So a mild win to AMD.
The I/O is a win for Intel due to DMI is 4.0x8 while X670E is PCIe4.0x4 like X570 bummer from AMD perhaps PCIe5.0 redrivers and layers cost.
IMC wise Intel is winning, but with DDR5 in this infancy stage even buying 7000MHz low Latency DRAM won't benefit RPL at all. AMD stuck to 6000MHz EXPO why did you not review on that ? I think AT should have stuck to XMP for Intel and EXPO for AMD as AMD will have better performance with better DRAM since the Zen 2 days. Ultimately IMC is bragging right for Intel DDR5 RPL now, the socket is EOL and you cannot install new Kits and expect magic just like 8th gen vs 10th gen IMCs you will need a new Chip.
Socket is dead end for Intel nothing extra is coming, you are locked out. AM5 will get Zen 4D and Zen 5 and 5D as well. Much better longevity past 2025+ if AMD launches Zen 6 then it's insane on this AM5 socket. Also Z790 will have CPU socket bending issues note that as well.AMD wins here.
Performance wise, both are neck to neck. High clocks on both high MT workloads on both camps, this is very interesting market for R9 and i9 parts. Coming to i5 and R5 parts, Intel has more performance but AMD has better pricing. However the most parts shipped will be this range only I think Intel may win more Client sales vs AMD due to DDR4. No winner but it's a great consumer choice. One point to note, AMD has higher Base Freq vs Intel this means better performance for AMD on all workloads and not just demanding. Esp with Zen 4 which is a solid chip than Zen 3 with it's lower clocks annoying IOD crapping out and IMC being subpar.
AVX512 is dead, big shame to Intel. They are wasting 30% of the die space in the RPL processors P cores, ultimate pathetic move. AMD is a champion with dual AVX256 making it solid no AVX offset performance unlike Intel 11th and 12th gen. AMD wins here. Reply

I hope this sad excuse from Intel shuts the facial orifices of those who thought the power draw of the 7950X was "too high"...;) These CPUs should sell well in colder climes, no doubt (for people who can afford the power bills...;)) ReplyWrs - Friday, October 21, 2022 - link
For workload efficiency it's mainly about the process tech. AMD with TSMC are at 5nm, Intel is still at 7nm (or you can say TSMC is around Intel's 7nm, while Intel is using its 3rd-gen 10nm).I like my P-cores on 12900k, thank you, they are the reason I didn't stick with Zen 3. A desktop computer needs to be highly responsive and it needs throughput when called for. I weigh those as 50% ST:50% MT, but everyone should personalize their ratio to what they really do. 90% ST:10% MT? Get a laptop. 10% ST:90% MT? A workstation or remote server/cloud.
I also have no issue with a D15 air cooler. The processor automatically tamps down to 250W sustained, but if I want something intense done, it'll blitz through the first second or two. As for power bill considerations, the Zen 3 did idle pretty high and I noticed. But on my desktop I rarely ever idle. It was more that a year ago, Zen 3 and Alder Lake were the same process generation, and Alder Lake hands down won the ST. Reply

So top of the line Raptor Lake trades blows/equals on average to Zen 4. But only if you have a motherboard/cooler capable of delivering and cooling 300+w, which means top of the line hardware. By the time you factor in the cost of a top notch MB and 360 AIO, you erase the price advantage of the processor itself.Limit i9 to similar power levels, and the performance would reduce more than just a few % I'd wager, so for those sticking with air cooling or smaller AIO's, Zen 4 has a clear advantage. This also points out that Raptor Lake doesn't have much headroom above this to go, where Zen 4 (if allowed 250w+) would clearly outperform RL at same power levels
Overall, this generation is much closer than I'd thought it would be, which as always is great for consumers Reply
