The AMD Ryzen 9 7950X3D vs Intel Core i9-13900K rivalry is a battle of flagships for the highest-end of the gaming market, however the chips take drastically totally different approaches to serving up main efficiency. The Core i9-13900K wields Intel’s 13th-Gen Raptor Lake x86 hybrid structure to sq. off towards AMD’s chiplet-based Zen 4 Ryzen 7000 chips, however AMD has a trick up its sleeve — the Second-Gen 3D V-Cache tech, which fuses on a 3D-stacked cache chiplet atop the processor to ship market-leading gaming efficiency. These two essentially totally different approaches have shaken up our checklist of the best CPUs for gaming, however every strategy has its respective strengths.

AMD’s $699 Ryzen 9 7950X3D is geared particularly for players trying to blast by CPU-limited video games whereas nonetheless having the threaded heft of 16 cores that stay aggressive within the heaviest of productiveness workloads. The Ryzen 9 7950X3D does lag opponents in some productiveness apps as a result of tradeoffs related to the 3D chip-stacking tech, and it does not speed up all video games equally. Nonetheless, one factor is for certain — it’s the quickest gaming chip available on the market.

The $589 Intel Core i9-13900K is Intel’s quickest gaming processor, and whereas it is not fairly as quick as AMD’s Ryzen 9 7950X3D in gaming, it has a a lot friendlier price ticket and serves up ultra-competitive efficiency in each gaming and productiveness apps. Intel additionally continues to assist DDR4 reminiscence to supply a less-expensive path for builders, reducing the bar for entry to flagship efficiency even additional. In the meantime, AMD’s choice to assist solely DDR5 has confirmed to be a pricing ache level.

The totally different strengths of those two chips make for a tough choice in the event you’re trying to decide one to your subsequent high-end construct. Under we have taken the Core i9-13900K vs Ryzen 9 7950X3D rivalry by a six-round faceoff to see which chips take the crown in our gaming and utility benchmarks, together with different key standards like energy consumption and pricing. Let’s have a look at how they stack up. 

Options and Specs: AMD Ryzen 9 7950X3D vs Intel Core i9-13900K

  Road/MSRP Cores / Threads (P+E) P-Core Base / Enhance Clock (GHz) E-Core Base / Enhance Clock (GHz) Cache (L2/L3) TDP / PBP / MTP Reminiscence
Ryzen 9 7950X3D $699 16 / 32 4.2 / 5.7   144MB (16+128) 120W / 162W DDR5-5200
Core i9-13900KS $699 24 / 32 (8+16) 3.0 / 6.0 2.2 / 4.3 68MB (32+36) 150W / 253W / 320W DDR4-3200 / DDR5-5600
Core i9-13900K / KF $589 (Ok) – $564 (KF) 24 / 32 (8+16) 3.0 / 5.8 2.2 / 4.3 68MB (32+36) 125W / 253W DDR4-3200 / DDR5-5600

AMD’s $699 Ryzen 9 7950X3D comes packing sixteen Zen 4 cores and the corporate’s second-gen 3D V-Cache tech that unlocks 128MB of L3 cache, a combo that delivers the quickest gaming efficiency obtainable available on the market. The 7950X3D has the identical underlying design because the Ryzen 9 7950X with a central I/O die and two eight-core compute chiplets that present a complete of 16 cores and 32 threads.

Not like the usual 7950X, one of many 7950X3D’s compute chiplets comes with an extra 3D-stacked L3 cache and boosts to five.25 GHz. In the meantime, the ‘commonplace’ compute chiplet with out cache boosts to five.7 GHz, the identical as the usual 7950X (details here). Regardless of the decrease frequency, the cache-equipped chiplet supplies the most effective efficiency for video games, whereas the quicker chiplet is finest for productiveness purposes. As such, AMD designed an progressive new driver that helps steer threads for several types of workloads to the proper chiplet.

The Ryzen 9 7950X3D brings the entire facilities we’d anticipate from a contemporary processor, together with assist for DDR5, PCIe 5.0, and the most recent USB connectivity requirements. AMD has additionally added built-in graphics for a primary show out for the primary time, which is a plus if it’s worthwhile to troubleshoot. You may see our iGPU testing here.

The 7950X3D sips energy — it has a base TPD of 120W and a max 162W PPT, which is 68W decrease than the 170W/230W ranking for the usual 7950X. The decrease energy threshold will end in much less efficiency in heavy purposes, however you may nonetheless have to plan for a 240mm to 280mm AIO (or higher) for the most effective efficiency.

The Ryzen 9 7950X3D requires an AM5 motherboard, so dear DDR5 reminiscence is the one choice. Sadly, DDR5 continues to be rather more costly than DDR4 reminiscence. Granted, that pricing strain is not as a lot of a consideration on the excessive finish, however you need to issue it into your buying choice. The AM5 platform is new, so the Ryzen 7000 chips aren’t backward suitable with older AM4 motherboards. Nonetheless, AMD will assist the AM5 platform till 2025+.

AMD solely allowed overclocking the reminiscence and Infinity Cloth for the previous-gen 5800X3D, however the 7950X3D additionally provides assist for each the auto-overclocking Precision Enhance Overdrive (PBO) and the Curve Optimizer. Sadly, AMD nonetheless doesn’t permit direct frequency overclocking attributable to a voltage limitation for one of many chiplets.

Intel’s $589 sixteen-core Core i9-13900K comes with eight hyper-threaded P-cores and 16 single-threaded E-cores, for a complete of 32 threads. That is a rise of eight further E-cores over the previous-gen Core i9-12900K, equating to extra threaded horsepower. It’s also possible to avoid wasting money with the $564 Core i9-13900KF, which has equivalent specs however lacks the built-in GPU.

Intel nonetheless makes use of the ‘Intel 7’ course of node for Raptor Lake however leveraged a more moderen revision of the silicon to push clock speeds larger whereas bettering energy effectivity. The P-cores include a 3.0 GHz base, however, extra importantly, a 5.8 GHz enhance that is a whopping 600 MHz enhance over the prior gen. In the meantime, the E-cores now have a 3.0 GHz base (+600 MHz) and stretch as much as 4.3 GHz (+400 MHz), which means that not solely do you get extra E-cores, however you additionally get extra out of every core.

The Core i9-13900K can be geared up with 32MB of L3 cache and 36MB of L2 and drops into present 600-series motherboards or the brand new 700-series fashions. The chip comes with the built-in UHD Graphics 770 engine with 32 EUs that enhance as much as 1.65 GHz.

Intel’s chips now have a Processor Base Energy (PBP) worth as an alternative of a TDP metric, and a secondary Most Turbo Energy (MTP) worth that denotes the best energy stage throughout enhance exercise. The 13900K comes with 125W PBP (base) and 253W MTP (peak) energy scores, however remember that the chip can at all times function on the 253W MTP when it’s underneath load, although the precise energy use will differ with utility depth. Intel permits full overclockability, however solely if you pair the chip with a Z-series motherboard.

Winner: Tie

The Core i9-13900K vs Ryzen 9 7950X3D battle yields a tie on this class. Each chips assist DDR5 and the PCIe 5.0 interface, which means neither has an inherent connectivity benefit.

Intel has the benefit of backward compatibility for DDR4 and the 600-series chipset, enabling lower-cost reminiscence and motherboards for worth seekers (caveats apply). Intel additionally has its Raptor Lake Refresh chips on the horizon, which means there will likely be another technology of upgrades for the LGA 1700 platform.

AMD’s new AM5 platform solely helps dear DDR5 and carries a premium over the Intel motherboard ecosystem, however it does afford prolonged ahead compatibility — AMD plans on supporting the AM5 platform till 2025+.

Given its new hybrid structure with two varieties of cores, Intel’s core counts aren’t straight similar to AMDs attributable to their totally different capabilities. Our efficiency outcomes will dictate the efficiency worth of the general designs.
