AMD Ryzen 9 7950X3D Desktop Processor (16-core/32-thread, 144MB cache, up to 5.7 GHz max boost)

Product Information

This asymmetrical L3 layout has consequences for dual-CCD chips such as the Ryzen 9 7950X3D and 7900X3D. Putting the right workload on the right CCD is one extra complication of the design. In practise, users want a seamless method of putting cache-heavy workloads – gaming being a prime example – on the 96MB L3 cache-infused CCD and small-footprint code on the regular CCD. It so happens AMD has an answer for this. Whaddya know, some games favour lots of cache. Catapulting to the top of the charts in no uncertain fashion, X3D technology can work really well. System scores are middling more than impressive, as these synthetic tests rely heavily on peak frequency. Surely it’s real games that count… Gaming No responsibility is taken for the correctness of this information. The listed offers do not constitute legally binding advertising claims of the merchants. We’re curious as to why AMD restrained power so much when a 170W TDP and associated 220W PPT is fine for 7950X. Is it really a case of ensuring an extra 64MB of L3 cache doesn’t overheat, or is there something more sinister going on? Putting our conjecturing hat on, equipping X3D with the standard 170W TDP would make regular 7950X redundant. Product positioning and all that.

There are hundreds of different cooling options for the AMD Ryzen 7000 Series, ranging from air CPU coolers, AiOs, to complete water-cooling systems. What you choose all depends on your individual preferences and needs. Performance is in line with expectations of a 120W part, though there’s no escaping the fact regular 170W 7950X is the superior chip for demanding multi-threaded work.This graph is helpful in pushing up efficiency; do recall 7950X3D ships with a 120W TDP. Like 7950X regular, we believe AMD ought to have let it run mostly free of wattage constraints – a 170W TDP 7950X3D would certainly benchmark that little bit better… but then what would be the point of 7950X regular? Decisions, decisions. Benchmark chops are healthy as a result, and the main reason it’s slower than, say, a Ryzen 9 7950X rests mostly with a lower power budget and final speed. Logs reveal the chip pushing past 5.6GHz when under light load. Put all cores to work and 7950X3D averages around 4.9GHz, but that only tells half the story. Our testing shows the standard CCD to push past 5GHz whilst the cache-enhanced CCD meters effort to 4.8GHz. If you are using your PC for light gaming, internet browsing, or watching YouTube, you won’t need a hefty custom water-cooling system. An air CPU cooler will be plenty. However, if you’re looking to enjoy the latest AAA titles, want to start streaming, or run more intensive applications, you will need powerful cooling in the form of an AiO or custom water-cooled loop. You need to protect yourself and the computers you use. But you don’t want to be slowed down or interrupted when you’re gaming online. No surprises in the memory department. The regular AIDA test doesn’t readily differentiate between CCDs so we can’t calculate the extra latency of hopping on over to X3D.

Internal components and lighting are entirely dependent on the specification of the components selected and may not be as displayed. Extracting more performance from CPUs is an inherently complicated business. Increasing frequency burns power, going architecturally wider burns die size, jumping down successive manufacturing nodes is damn expensive. Who’d be a CPU lead architect? New problems arise faster than extant ones are solved. Fundamental limitations ought to encroach on step-change improvements from one generation to the next, yet AMD and Intel continue to deliver in spades. Today’s best Ryzen 9 and Core i9 chips smash predecessors from merely three years’ ago. In Darth’s seminal words, ‘impressive, most impressive.’ The cores, and by extension operating system, are oblivious to the bonding of extra L3. X3D appears and largely performs like a triple-dense L3 monster. We say largely as there is a minor overhead of four cycles in accessing the upper cache, but that’s a pretty good return all things considered. 3D V-Cache as implemented on Zen 3, which is the same as Zen 4 Hefty performance requires ample cooling. The more advanced your chosen processor is, the higher the TDP will be. TDP stands for ‘Thermal Design Power’ and refers to the maximum amount of heat generated. The AMD Ryzen 7000 Series has been optimised for gaming and streaming alike, promising to deliver ultra-fast speeds and powerful performance. To fully utilise the incredible benefits offered by these processors, you need a reliable and efficient CPU cooler to match.After traditional levers have been twiddled and optimised to the nth degree, out-the-box thinking is required to increase performance without resorting to the age-old, sledgehammer technique of slamming as much power through the best CPU as possible. AMD believes it has uncovered a gem in X3D technology. First seen on Ryzen 7 5800X3D, the latest 7000 Series range is receiving cache-enriched upgrades to not one but three processors. Ryzen 9 7950X3D and Ryzen 9 7900X3D stride forward today, with Ryzen 7 7800X3D arriving April 6. Leveraging the same technology we first witnessed with the impressive Ryzen 7 5800X3D, suffusing more L3 cache is inherently more difficult on two-CCD processors such as the review Ryzen 9 7950X3D and 7900X3D. The asymmetrical design and restrained power budget work well enough to deliver the same level of overall gaming performance as MadWattage™ Core i9-13900KS, which is a feat in itself. The first part is a 3D V-Cache performance optimiser driver that’s included in chipset software 5.01.03.005 or newer. According to AMD, ‘the driver evaluates the performance in real time and dynamically modifies the preferred cores seen by Windows based on workload preference for the 3D V-Cache CCX or the standard die.’ Run automatically for best performance, behaviour can be overridden by the user for manual tinkering. Another solid set of results. Zen 4 has previously shown good aptitude when running at lower wattages; 7950X3D carries on the good work. Though the focus ought to rightfully be on gaming performance first and foremost, let’s remember this is a 16-core, 32-thread chip empowered with the full might of the Zen 4 architecture.
