Intel Core i9-13900K and i5-13600K Review: Raptor Lake Brings More Bite

Rendering tests, compared to others, are often a little more simple to digest and automate. All the tests put out some sort of score or time, usually in an obtainable way that makes it fairly easy to extract. These tests are some of the most strenuous in our list, due to the highly threaded nature of rendering and ray-tracing, and can draw a lot of power.
If a system is not properly configured to deal with the thermal requirements of the processor, the rendering benchmarks are where it would show most easily as the frequency drops over a sustained period of time. Most benchmarks in this case are re-run several times, and the key to this is having an appropriate idle/wait time between benchmarks to allow for temperatures to normalize from the last test.
One of the interesting elements of modern processors is encoding performance. This covers two main areas: encryption/decryption for secure data transfer, and video transcoding from one video format to another.
In the encrypt/decrypt scenario, how data is transferred and by what mechanism is pertinent to on-the-fly encryption of sensitive data - a process by which more modern devices are leaning to for software security.
We are using DDR5 memory on the Core i9-13900K, the Core i5-13600K, the Ryzen 9 7950X, and Ryzen 5 7600X, as well as Intel's 12th Gen (Alder Lake) processors at the following settings:
- DDR5-5600B CL46 - Intel 13th Gen
- DDR5-5200 CL44 - Ryzen 7000
- DDR5-4800 (B) CL40 - Intel 12th Gen
All other CPUs such as Ryzen 5000 and 3000 were tested at the relevant JEDEC settings as per the processor's individual memory support with DDR4.
Rendering
Identifying what core comes where in our rendering tests, both the Core i9-13900K and Ryzen 9 7950X sit comfortably at the top of the tree. Depending on the test, it’s a consistent battle for rendering supremacy. Where things aren’t as close are in our POV-Ray and V-Ray tests, where the Core i9-13900K has a distinct advantage; likely down to having eight more logical cores than the 7950X.
Encoding
In our encoding tests, interestingly the Core i9-13900K looks to have the advantage in compressing files with 7-Zip. It’s a little different for AMD as the Ryzen 9 7950X decompresses the data better, with the overall combined advantage going to AMD in this particular test. In our updated x264 benchmark, Intel takes the lead in 4K encoding, while AMD has the lead in 1080p encoding; both are equally viable options, however.

x264 is (more or less) the same thing as the handbrake test... and it kinda is legacy software at this point.Personally, I'd like to see a more modern encoding test, like av1an with x265+chunked encoding, or maybe Staxrip with some filters enabled. Reply

Yes, some libaom would be fantastic. Replyjakky567 - Monday, October 24, 2022 - link
I wouldn't say handbrake/x264 are obsolete yet. We should be looking towards the future, but h264 is here to stay as at least a fallback codec. ReplyGeoffreyA - Tuesday, October 25, 2022 - link
It is very much the MP3 of video and here to stay. Plus, its successors have not been indisputably better or have come with tradeoffs. ReplyAshantus - Thursday, October 20, 2022 - link
Comparing the performance of 7600X vs 13600k i see some overall advantage for the 13600K.But, i will defionitly go for the 7600X due one argue.
Load Consumption of 134 Watt vs 238 Watt at almost same performance is something.
Regarding the poweer costs in europe of 60 cent per Watt that is quiet some pricing argue at a 5 years lifetime.
At anandtech:
this argue should be mentioned in your closing thoughts. 100 Watt more powerconsumption at todays powerprices is a serious issue. Reply

I don't remember seeing power versus performance numbers. Did I miss them? ReplyCiccioB - Thursday, October 20, 2022 - link
<blockquote>Load Consumption of 134 Watt vs 238 Watt at almost same performance is something.</blockquote>This thought is completely wrong. It is called "induction", as you were looking at something and then reported that on something else.
You see a graph of power consumption for a "unlimited test" (where performance is not measured) and then you think that that measure is valid also for other tests.
So you just think that for each bench those CPUs consume always those Watts (how can it be?) and that the performance are the same (where did you got that? In almost all benches the 13600K leaves the 7600X in the dust, but not knowing their power consumption for those test you cannot say which is the most efficient). Reply

Just found another test, whereas a powerconsumption at action is recorded.At gaming (average out of 12 games tested) is:
13600k = 88 W. 7600X = 60 W
13990K = 144 W 7900X = 107W Reply

that looks more plausible. but it is also mostly useless except in the context of the specific workload. modern cpu performance testing is very complicated and performance versus power should be taken in the specific workload one is interested in, or at the very least an average of workloads of a similar type.

Specific workload such as : 13990K produces 100 fps @ 144 W, while 7600X produces 100 fps @ 60 W? Reply
