This is a fast take a look at the typical of our high gaming benchmarks and productiveness apps exams, however make sure you go to the remainder of the exams on the following pages to see particular person benchmark outcomes and overclocked configurations.
AMD’s costly Ryzen 9 7950X3D and its sibling, the 7900X3D, have been enormously appreciated, however the firm held again the less expensive Ryzen 7 7800X3D till April 6. From a enterprise standpoint, that makes lots of sense—the 7800X3D presents barely extra gaming efficiency for $250 lower than the flagship, which does not depart a lot cause to purchase the flagship in the event you’re solely eager about gaming. In actual fact, if peak gaming efficiency is your solely concern and also you’re on a finances, we discovered that the Ryzen 7 7800X3D leaves little room for every other chip – nicely above the remainder. That stated, Intel is not sitting on the sidelines both, as Raptor Lake alternate options supply their very own perks. Let’s have a look at how the chips stack up in our gaming exams on the next pages.

It heralded the arrival of the Ryzen 7 7800X3D when AMD first launched the Ryzen 7000 sequence, with a obvious ‘7800X’ hole between the Ryzen 7 7700X and Ryzen 9 7900X. When it comes to gaming efficiency, the Ryzen 7 7800X3D ranks in opposition to (and beats) Intel’s $580 24-core 32-thread Core i9-13900K, however with the $417 16-core 24-thread Core i7-13700K extra carefully matched. by way of pricing and efficiency in productiveness purposes.
The 7800X3D is considerably much like the Zen 3-powered Ryzen 7 5800X3D with eight cores, 16 threads and 3D V-Cache know-how on each chips, however the similarities finish there. The Ryzen 7 7800X3D steps as much as the Zen 4 structure and contains a 500 MHz increased 5.0 GHz increase frequency and an 800 MHz increased 4.2 GHz base clock; all of which supply a lot higher efficiency in video games and a greater variety of purposes. As we’ll present on the following web page, AMD may have run the 7800X3D at increased velocity however selected to cease at 5.0 GHz.
From the fashionable Zen 4 household, the Ryzen 7 7700X is the closest comparability with the identical cut up of eight cores and 16 threads, however comes with out 3D stacking know-how and has a 300MHz increased base and 400MHz increased increase clock than the 7800X3D. . It’s because the Ryzen 7 7800X3D has eight cores in a single computing die powered by a 7nm SRAM slice of hybrid bonded L3 cache on silicon. This cache chip creates thermal challenges, which you’ll examine right here, leading to a 1.1 V voltage limitation and decrease peak frequencies than customary chips, a crucial adaptation to maintain thermals in test.
AMD’s 3D V-Cache know-how takes the important thing benefits of chip-based design methodologies into the third dimension by inserting an older and cheaper 7nm course of node on high of cores etched into costly new 5nm course of know-how. Like all different 3D V-Cache chips, the 3D stacked SRAM L3 chip weighs 64MB. In consequence, the 7800X3D comes with a complete cache of 104MB, of which 96MB is the game-boosting L3 cache. The extra L3 cache chip has a peak bandwidth of two.5 TB/s, which is 25% sooner than the earlier era implementation. You may learn the finer particulars of Second Technology 3D V-Cache know-how right here.

| Header Cell – Column 0 | 65W TDP | 105W TDP | 120W TDP (X3D) | 170W TDP |
|---|---|---|---|---|
| Socket Energy (PPT) Watts | 88W | 142W | 162W | 230W |
| Peak Present (EDC) Amps | 150A | 170A | 180A | 225A |
| Steady Present (TDC) Amps | 75A | 110A | 120A | 160A |
All of AMD’s Zen 4 3D V-Cache processors have a base TPD of 120 W and a most PPT of 162 W, so the 7800X3D’s scores are 15/20 W. increased greater than the 105W/142W ranking for the usual 7700X. In distinction, the multi-chip 7950X3D and 7900X3D have decrease energy thresholds than their equivalents as a result of the extra cache chip causes barely increased working temperatures that should be stored inside a secure vary.
Nonetheless, the Ryzen 7 7800X3D’s increased TDP threshold would not make a lot sense — as you will see on the following pages, the chip by no means got here near its rated energy limits and the thermals have been simple to tame. Talking of, the 7800X3D’s most supported temperature is 89C, decrease than the 7700X’s restrict of 95C. The 7800X3D doesn’t include an included cooler — AMD recommends a 280mm water cooler or higher for Ryzen 7000X3D processors.
As with all Ryzen 7000 chips, the Ryzen 7 7800X3D’s RDNA 2 built-in GPU has two computing items, 4 ACEs and 1 HWS. This unit would not have the horsepower to make the most of the sooner CPU cores — it is totally depending on GPU computing. The iGPU additionally doesn’t profit from 3D V-Cache know-how because it resides on the I/O die and can’t entry the L3 cache, so efficiency is similar as common Ryzen 7000 processors (see extra on our X3D iGPU to check).
Whereas the earlier era Ryzen 7 5800X3D makes use of the getting older AM4 platform with much less superior interfaces equivalent to PCIe 4.0 and DDR4 reminiscence, the Ryzen 7 7800X3D plugs into AM5 motherboards that assist the most recent connectivity know-how equivalent to DDR5 and PCIe 5.0. AMD solely allowed overclocking of reminiscence and Infinity Material for the earlier era 5800X3D, however now permits each auto-overclocked Precision Increase Overdrive (PBO) and Curve Optimizer. AMD nonetheless doesn’t permit direct frequency overclocking because of the voltage limitation talked about above as a consequence of 3D V-Cache. Now we have lots of exams for these options on the following pages — go to our overclocking web page for particulars.
Whereas we ran right into a snag in our testing as a consequence of a driver anomaly we reported to AMD, the Ryzen 7 7800X3D ought to profit from the simplicity of a single compute chip design.
The Ryzen 9 7950X3D and 7900X3D have two octa-core Core Compute Die (CCD) chips paired with a central I/O Die; Which means that AMD is bringing 3D V-Cache know-how to the multi-CCD processor for the primary time. The picture above exhibits AMD putting in only a single 7nm SRAM chip on high of one of many two octa-core CCDs, leaving the opposite naked. Which means that every kind of chip is finest suited to several types of work — the 3D V-Cache-capable chip is finest for cache latency delicate duties like gaming, and the usual chip is for workloads that reply finest to increased frequencies.
You may learn the in-depth particulars of AMD’s thread focusing on implementation right here, however the important thing takeaway is that it requires 4 completely different parts to work collectively to routinely swap thread assignments to cores.
Against this, whereas we do not have a Ryzen 7 7800X3D (or perhaps a render) picture at hand, it solely comes with one of many two small rectangular CCDs seen within the picture. Which means that none of those mechanisms are essential to direct threads to the right chip – there is just one chip, so the processor will perform usually. Let’s have a look at what the efficiency appears like on the next pages.
