By utilising 3D V-Cache technology, which enables AMD to stack sizable cache pools on top of Zen chiplets, AMD introduced the Ryzen 7 5800X3D last year. This CPU was created to provide gamers with the best value and performance possible, increasing performance in bandwidth-constrained games and applications. Reviews revealed a significant improvement in gaming performance that at the time matched or even surpassed Intel’s fastest CPU, the Core i9-12900K, so the benefit was immediately apparent.
AMD intends to do the same with the Ryzen 7000 X3D components, giving gamers an additional boost that might make AM5 the fastest gaming platform.
Expected Features for AMD Ryzen 7000 X3D “Zen 4” 3D V-Cache Desktop CPUs:
- Minor improvement on the 5nm manufacturing node of TSMC
- Stacked cache of up to 64 MB for each CCD (96 MB L3 per CCD)
- Performance in Games Has Improved (Avg & Mins)
- Equivalent To AM5 Platforms
Specs for the AMD Ryzen 7000 X3D CPU lineup
The 2nd generation consumer stacked cache V-Cache CPUs are the AMD Ryzen 7000 3D V-Cache CPUs. The Zen 4 lineup will include three SKUs at wildly different price points, whereas the Zen 3 lineup only included one 3D V-Cache SKU.
16 Cores, 144 MB Cache AMD Ryzen 9 7950X3D
The AMD Ryzen 9 7950X3D, which will be the top model and the first 16-core CPU with 3D V-Cache technology, is at the top of the list. A total of 32 threads, 144 MB of cache (64 MB CCD, 64 MB V-Cache, and 16 MB L2), and a TDP of 120W are all features of the chip. In terms of frequency, the chip is listed at 4.2 GHz base clock, which is 300 MHz slower.
The AMD Ryzen 9 7950X3D, which will be the top model and the first 16-core CPU to support 3D V-Cache, comes first. The chip will have a TDP of 120W, a total of 32 threads, and 144 MB of cache (64 MB CCD, 64 MB V-Cache, and 16 MB L2). The chip’s base speed is 4.2 GHz, which is 300 MHz slower than the normal 7950X, however boost clocks are still specified at the same 5.7 GHz. This ought to provide us with some insight into why the TDP is 50W lower than the Non-3D component.
By placing the SRAM cache on a single CCD rather than both CCDs, AMD is structuring the 3D V-Cache on the Ryzen 9 X3D components. In this manner, AMD may maintain the extra die to take advantage of the higher clock speeds while still maximising performance in gaming with a single CCD (1T). This means that, unlike the previous generation, there should be a balance between the performance of single- and multi-threaded applications. The cache die has to be optimised significantly because this chip is mostly intended for gaming. It will be fascinating to watch how things turn out in the retail units as they are finalised and how much tuning AMD allows for the new parts.
Ryzen 9 7900X3D from AMD, 12 Cores, 140 MB Cache
The AMD Ryzen 9 7900X3D, which has 12 cores and 24 threads, is the second processor. This arrangement likewise uses two CCDs, one of which has the V-Cache enabled and the other does not. The chip has 140 MB of cache in total (64 MB CCD, 64 MB V-Cache, and 12 MB L2). The base clock is rated at 4.4 GHz, 200 MHz less than the Non-3D SKU, and the boost clock stays at 5.6 GHz. Additionally, the CPU has a TDP of 120W.
AMD Ryzen 7 7800X3D – The New Gaming Champ, Replacing The 5800X3D!
The Ryzen 7 7800X3D is the model that succeeds the Ryzen 7 5800X3D. With 8 cores, 16 threads, and the same 104 MB of cache (32 MB CCD, 64 MB V-Cache, and 8 MB L2), this CPU will be the best option for gamers. The CPU has a boost rate of 5.0 GHz, which is 400 MHz slower than the Ryzen 7 7700X, and a base clock of about 4 GHz, which could wind up being at least 500 MHz slower than the Ryzen 7 7700X.
Performance of AMD Ryzen 7000 X3D CPU
Since AMD wants the independent tech sector to test these chips later this month and present their own data rather than depending on official stats, they haven’t shared a lot of performance information, which is fair. Performance data for the two Ryzen 7000 X3D CPUs, the Ryzen 9 7950X3D and Ryzen 7 7800X3D, was provided.
AMD compared the Ryzen 9 7950X3D CPU to Intel’s flagship Core i9-13900K CPU using a variety of workload and gaming applications. According to the findings, a 1080p 3D V-Cache chip can provide up to 24% faster performance when playing games with good image quality. The game tests and corresponding improvements over the 13900K CPU are listed below:
Performance Test for AMD Ryzen 9 7950X3D Gaming (provided by AMD):
- 9% faster in Watch Dogs Legion (1080p)
- DOTA (1080p) (1080p) Up to 11% quicker
- The Rainbow Six Siege (1080p) Up to 13% quicker
- Frontier Zero Dawn (1080p) – Up to 24% quicker
Because of the 3D V-Cache stacking, the 7950X3D chips have different CCD configurations, with one operating at faster clock speeds and the other having more restrictive clock restrictions. However, even in demanding apps, the chip can perform better than a Core i9-13900K CPU in a variety of tests, as seen below:
Workload Performance Test on AMD Ryzen 9 7950X3D:
- VeraCrypt AES File Encryption – Up to 4% more rapid
- 3D graphics (PassMark 10) – Up To 11% Faster
- Premiere Pro by Adobe (Playback) – Up To 17% More rapid
- DaVinci Resolve (Extended Score) – Up To 24% accelerated
- file compression (7-Zip) – Up To 52% Faster
The AMD Ryzen 7 7800X3D has also been compared to the Ryzen 7 5800X3D, with even more astounding results. With all games set to the same 1080p resolution and high quality, the CPU outperformed the first-gen X3D CPU in gaming by up to 30%. The benefits are shown below:
- The Rainbow Six Siege (1080p) – 21% Faster, Up To
- Third Warhammer Dawn of War (1080p) – Up to 22% quicker
- CS:GO (1080p) (1080p) Up to 23% quicker
- Dota 2 (1080p) (1080p) – Faster by up to 30%
These are unquestionably significant advances for gamers, and the addition of Ryzen 9 components means that customers will have the fastest gaming and content creation capabilities available. The minimum FPS range will also significantly increase as a result of V-Cache, which AMD isn’t yet revealing, but we can’t wait to see more precise performance data.
CPU Power & Thermals for AMD Ryzen 7000 X3D
The development of 3D V-Cache chips is significantly influenced by the power and thermal restrictions. The SRAM itself is a pretty delicate semiconductor component to work with, which makes the stacked V-Cache chips different from your typical Ryzen CPU. As a result, AMD has decreased the TDP overall, fixed the voltage, and decreased the TjMax temperature thermal restrictions.
While the CPUs can easily reach the TjMax of 95C for the current Zen 4 lineup, AMD assures consumers that they need not worry because this type of operation is within specification. As AMD’s GPUs also have a peak temperature restriction of up to 110C, which is deemed to be “Normal Spec,” these high-temperature limits appear to be the norm for AMD these days.
A TjMax of just 89C has been recorded for the trio of AMD Ryzen 7000 X3D CPUs, which consists of the Ryzen 9 7950X3D, Ryzen 9 7900X3D, and Ryzen 7 7700X3D. This is 6C lower than the 95C TjMax of the Ryzen 7000 Non-3D CPUs.
The maximum voltage for AMD’s Ryzen 7000 X3D CPUs is 1.4V, an increase of 0.3V over the Ryzen 7 5800X3D. (1.1V). The new CPUs will include automatic overclocking features like PBO and Curve Optimizer, but human overclocking is prohibited because of the 3D V-erratic Cache’s behaviour when layered on top of a single CCD. High temperatures and high voltages might harm the chip or cause unexpected behaviour.
Although the Windows 11 OS has already optimised the hybrid layout of dual CCD SKUs like the Ryzen 9 7950X3D and Ryzen 9 7900X3D, it is still unknown how high temperatures will effect how well these components run their clocks. If you want to stay below the 89C limit, you will undoubtedly need some sophisticated cooling systems. That may also be the reason AMD decided to use a lower 120W TDP on the higher-end SKUs to prevent them from consuming too much power and hitting the thermal wall. Manual overclocking is strictly prohibited, as expected, although AMD has enabled support for Curve Optimizer and PBO, which wasn’t feasible on first-generation 3D components.
Overclocking AMD Ryzen 7000 X3D
Yes, all three Ryzen 7000 X3D CPUs will support AMD EXPO memory along with the overclocking tools Curve Optimizer and Precision Boost Overdrive. The best overall CPU performance is delivered via Curve Optimizer, which AMD advises users to use. However, hard frequency overclocking is restricted, much like with Zen 3D V-Cache processors from the previous generation.
Support for AMD Ryzen 7000 X3D CPU
AM5 motherboards will support all AMD Ryzen 7000 X3D CPUs. To ensure the best compatibility on the new hardware, users will need to instal the most recent chipset drivers and perform a manual BIOS firmware update. This month, new motherboards that support these CPUs without requiring BIOS upgrades will also be introduced.
Price & Availability of AMD Ryzen 7000 X3D CPU
Finally, let’s talk about the cost and accessibility. The AMD Ryzen 9 X3D CPUs will be the first to hit store shelves on February 28. The Ryzen 7 X3D CPU is scheduled to go on sale just over a month later, on April 6. It is clear that AMD aims to target premium users before entering the market with the mainstream X3D solution at under $500 US. As is the case with the 5800X3D, which has been the top-selling CPU at various stores for several months due to its incredible price-to-performance value in the gaming market, having that available right away would cause it to gobble up the sales of the higher-end parts.
At launch, the AMD Ryzen 9 7950X3D will cost $699 US, which is the same MSRP as the original 7950X before it was discounted to $599 US. That costs $100 US more than Intel’s i9-13900K.
On February 28, the AMD Ryzen 9 7950X3D and 7900X3D will go on sale for the same $599 US price as the already available 7950X. It appears that AMD believes the 7900X3D will perform significantly better in games than the i9-13900K at the same price point.
The AMD Ryzen 7 7800X3D, which costs $449 US, is the last option. That costs about $100 US more than the Ryzen 7 7700X and $30 US more than the Core i7-13700K, but again, this is the chip that many gamers have their sights set on, and it has the potential to be an incredibly disruptive gaming product from AMD.
