Ryzen 9 7900X3D vs i9-12900KS, which is best?
Up to date: Feb 28, 2023 10:51 am
The Ryzen 9 7900X3D is likely one of the two Ryzen 7000X3D processors that have been launched on February twenty eighth, 2023, the opposite being its elder brother, the 7950X3D. The 7800X3D, sadly, had its launch postponed to April.
Now learn: Is Ryzen 7000X3D worth it
On this article, we’re evaluating the newly launched 7900X3D with the last-gen flagship, the Core i9 12900KS, to learn the way the 2 differ. That is Ryzen 9 7900X3D vs i9-12900KS.
Ryzen 7 7900X3D vs i9-12900KS: CPU specs
Let’s first take a look on the official specs for each processors to get a greater thought of what we’re working with.
Ryzen 9 7900X3D
- Core depend: 12 (Multithreading enabled)
- Thread depend: 24
- Core clock: 4.4GHz
- Increase clock: 5.6GHz
- L2 cache: 12MB
- L3 cache: 128 MB
- TDP: 120 watts
- iGPU: Radeon Graphics
- Socket: AM5
The R9 7900X3D has specs similar to the standard 7900X. Probably the most notable exception, in fact, is the supply of a large 128MBs of L3 cache to the CPU cores.
The existence of such an absurd quantity of cache on the CPU die is made attainable by AMD’s 3D V-cache know-how, which entails stacking cache vertically slightly than horizontally on the die.
Intel Core i9-12900KS
- P-cores: 8 (Hyperthreading enabled)
- E-cores: 8
- Thread depend: 24
- P-core clock velocity: 3.4 / 5.5 (GHz)
- E-core clock velocity: 2.5 / 4.0 (GHz)
- L2 cache: 14MB
- L3 cache: 30MB
- Base TDP: 150W
- Max TDP: 241W
- iGPU: UHD770
- Socket: LGA1700
Launched in early 2022, the Core i9-12900KS remained Intel’s flagship processor for the higher a part of final 12 months. We now have stronger processors obtainable within the firm’s thirteenth gen lineup, however the 12900KS stays very aggressive and is definitely a becoming processor to place up towards the 7900X3D.
Ryzen 9 7900X3D and i9-12900KS in contrast
Right here we talk about how the 2 processors differ in efficiency, energy utilization, and extra.
Gaming efficiency
Gaming efficiency has traditionally boiled right down to single-threaded efficiency. However we now have a brand new influencing issue on the rise – cache measurement.
The cache is basically high-speed reminiscence positioned proper on the CPU die. Having extra of it signifies that the processor has to entry the a lot slower RAM much less usually, rushing up efficiency in sure workloads.
Because it occurs, gaming is the right instance of a workload that advantages noticeably from the supply of the additional L3 cache.
Statistically, we see that the Ryzen 9 7900X3D and the i9-12900KS have almost an identical most clock speeds (5.6GHz vs. 5.5GHz).
The slight nuance right here – all game-related processing on the 7900X3D is simply carried out on the V-cache enhanced CCD, which has a decrease max clock velocity of simply above 5GHz. Primarily, it’s the 12900KS’ threads which might be working barely sooner throughout gaming.
Nevertheless, regardless of that reality, the 7900X3D comes out on prime in gaming efficiency, purely because of the nice profit most video games are capable of derive from the additional L3 cache.
The 7900X3D delivers extra FPS in most mainstream titles, and the precise quantity varies based mostly on how properly a particular title is ready to make the most of V-cache. However, roughly talking, we’re taking a look at FPS positive factors of 10 to twenty% over the 12900KS.
Workstation productiveness
For productiveness, each processors ship fairly related efficiency. They’ve an analogous quantity of threads working at very related clock speeds.
Whereas the 12900KS does have extra bodily cores, half of the cores it does have are smaller effectivity cores, so the elevated core depend finally ends up probably not amounting to a major distinction in multithreaded workloads.
The 7900X3D’s additional cache doesn’t profit typical workstation workloads by a exceptional margin, so each processors finally find yourself offering very related productiveness efficiency attributable to their related specs.
Energy consumption and thermals
The Core i9-12900KS is extraordinarily power-hungry, with the power to attract upwards of 250 watts of energy at most load. The 7900X3D has a way more average 120-watt TDP. Provided that it delivers related or better efficiency than the i9-12900KS, it’s leaps and bounds extra vitality environment friendly than the i9.
The 7900X3D might be air-cooled (though an AIO is beneficial), however with the 12900KS, it’s important to go together with an costly top-of-the-line AIO to maintain temperatures below management.
Last phrase
In gaming, the Ryzen 9 7900X3D delivers extra frames than the 12900KS due to its V-cache enhancement. In multicore processing, each processors are about neck and neck. And when it comes to energy consumption, the 7900X3D is way more environment friendly and produces much less warmth.
