AMD Ryzen 9 7945HX3D Zen4 analysis - The fastest mobile gaming processor thanks to 3D V-Cache

Better performance in 1080p & QHD.

In the field of desktop PCs, AMD processors with 3D cache have existed for quite some time, but the announcement of the Ryzen 9 7945HX3D marks the first mobile processor with 3D V-Cache coming onto the market. According to AMD, this is now the fastest gaming processor - which we have analyzed.

At the beginning of April, we were able to test the new Ryzen 9 7945HX mobile processor, which is a direct competitor to Intel's high-end chip, the Core i9-13980HX. The results were conclusive, as its multi-core performance was higher - but its efficiency was the real star of the show. While the Intel CPUs consume upwards of 170 watts, the Ryzen 9 7945HX offers comparable performance while only using 80 - 100 watts.

AMD has already offered desktop CPUs with 3D V-Cache since last year and now, the Ryzen 9 7945HX3D is the first mobile processor which features this technology. Aside from the new 3D V-Cache (an additional 64 MB), its specifications are identical to the regular Ryzen 9 7945HX, meaning it features 16 cores/32 threads with a maximum clock of 5.4 GHz. In the case of the 7945HX3D, its normal cache (80 MB L2/L3 cache) has been expanded by a further 64 MB L3 cache. In doing so, the additional cache module is situated directly on the Zen4 CCD, which is slightly slimmer than the regular Zen4 CCD, leading to an identical build height. Apart from its additional cache, it also features structural silicone which allows the cooling unit to take up the entire surface. Especially at high frame rates, this is supposed to improve performance, since access time can be shortened and new data can be provided faster.

AMD also claims that the 3D V-Cache has a positive effect on low TDP values according to internal tests and has compared 70 and 40 watts with and without 3D V-Cache. However, we cannot verify this with our test systems. The Ryzen 9 7945HX3D is currently only available in the new Asus ROG Strix SCAR 17 X3D.

The Asus ROG Strix SCAR 17 X3D is currently the only gaming laptop featuring the new Ryzen 9 7945HX3D to enter the market. We have already tested the SCAR 17 with the regular Ryzen 9 7945HX and aside from its processor, its configuration with the GeForce RTX 4090 Laptop and the 240-Hz QHD panel is identical. Due to the new processor's surface texture, Asus now can't use liquid metal to dissipate heat from it - this makes itself known if you take a look at its maximum power consumption values. On the Ryzen 9 7945HX3D, it takes in 115 watts for a very short amount of time, then it balances out at 100 watts.

Please note: For our efficiency measurements, we used the consumption rates on an external monitor in order to rule out the internal display as an influencing factor. As already seen on the last ROG Strix SCAR 17, all display outputs run via the dedicated GPU which, as a result, is always active as soon as you use an external monitor. Of course, this has an effect on the measurements to a certain extent, especially when it comes to its single-core efficiency.

Single-core performance

Its single-core performance is practically identical to the regular Ryzen 9 7945HX and in turn, is considerably faster than the old Zen3 models such as the Ryzen 9 6900HX. Intel's Core i9-13900HX is also comparable - only the Core i9-13980HX benefits in total through its single-core turbo.

When taking a look at the results, you can't forget that the AMD Zen4 core consumes around 27 watts under single-core load, while the new Raptor Lake HX CPUs' performance core consumes 34 - 36 watts. This means AMD's pure CPU efficiency is better than Intel's. The fact that the dedicated Nvidia GPU was active for our power consumption measurements using an external monitor, of course, distorted our results - it is important to keep this in mind. For the sake of completeness, however, we have still included these values. You might actually see this as a positive, as even with its activated dGPU, our test device with the new Ryzen 9 7945HX3D was on the same level as the Intel Raptor Lake HX chips, which had an inactive iGPU during its measurements.

Multi-core performance

During the multi-core test, we became aware of its slightly weak cooling - here, the new Ryzen 9 7945HX3D narrowly avoided being able to compete with the models featuring the regular Ryzen 9 7945HX. In total, the new Zen4 processor with 3D V-Cache still came ahead of its Intel competitors which, in addition, consume more power. However, if you require the maximum CPU performance, then you should go for a device with the regular Ryzen 9 7945HX which uses liquid metal.

* ... smaller is better

When taking a look at its efficiency, you again have to remember that the dedicated GPU was active. Due to its higher total consumption, the influence is smaller here compared to during the single-core tests. The new Ryzen 9 7945HX3D came ahead of both of the regular 7945HX CPUs in turbo mode, which is the sole result of the lower power limits. If they both had identical power limits (e.g. 100 watts), then both models' efficiencies would be comparable. Here, you can also see AMD's advantage over Intel, whose CPUs simply require more energy in order to offer similar performance levels. Apple, with its M2 Max processor, came ever so slightly ahead - but in total, it offers notably lower maximum performance.

Performance with lower power limits

We were able to set new fixed power limits for the processor via the manual mode found in the test device's Armoury Crate software - unfortunately, we were more limited on the 7945HX3D. Due to its weaker cooling, the processor couldn't even complete the short Cinebench R23 run with a fixed limit of 115 watts - plus, this time, the app only allowed a minimum value of 65 watts. Both results at 100 watts and 80 watts were about on the same level as the regular Ryzen 9 7945HX. Here, you can also say that the Ryzen 9 7945HX3D offers better performance at 80 watts than the Intel Core i9-13980HX can at 150 watts.

Gaming performance 1080p

Now coming to the gaming benchmarks, where we have first taken a look at Full HD resolution. Here, the new Ryzen 9 7945HX3D was really able to show its advantages in quite a few games - we even noted it leading by two-figure percentage points at times. In Far Cry 5, we noted a whopping 36 % improvement compared to the regular Ryzen 9 7945HX as well as Intel's HX CPUs. In some games, we didn't measure any improvement, such as in The Witcher 3 and Call of Duty Modern Warfare 2.

Gaming performance QHD

In QHD resolution, the new processor also showed some advantages, although these were not as big as in 1080p. In general, the Ryzen 9 7945HX3D still offers better performance than its competitors - again by up to two-figure percentages at times.

Gaming performance 4K

In 4K resolution, the new Ryzen 9 7945HX3D doesn't offer any advantage compared to the regular Ryzen 9 7945HX or Intel's mobile HX processors, although all of the models performed on a very similar level.

Verdict - The Ryzen 9 7945HX3D is the fastest gaming processor

The AMD Ryzen 9 7945HX3D in the new Asus ROG Strix SCAR 17 X3D
The AMD Ryzen 9 7945HX3D in the new Asus ROG Strix SCAR 17 X3D

After running our tests, it is clear that AMD's new Ryzen 9 7945HX3D is the fastest gaming processor. Its additional 3D V-Cache makes itself especially known in Full HD resolution and offers a considerable advantage (at times two-figure percentages) in many games compared to the regular Ryzen 9 7945HX and Intel's mobile HX processors. This is quite the performance, but you do have to question whether users of a high-end gaming laptop will really play games in 1080p resolution. For example, the test device Asus ROG Strix SCAR 17 features a QHD panel and although we did still note a benefit in quite a few games, the difference compared to other processors becomes smaller. Gaming in 4K at the latest is unable to offer any improvement. 

The new AMD Ryzen 9 7945HX3D is the fastest mobile gaming CPU on the market which additionally offers 3D V-Cache and an has especially large advantage over its competitors when it comes to gaming in 1080p resolution. Its advantage already becomes more limited in QHD resolution.  

All-in-all, its pure CPU performance is identical to the regular Ryzen 9 7945HX and especially its multi-core efficiency in comparison to Intel's HX processors is phenomenal. Even with a fixed 80-watt power limit, the Ryzen is still faster than Intel's Core i9-13980HX at 150 watts. The same can be said for the regular Ryzen 9 7945HX without 3D V-Cache. The new processor does come with a disadvantage: Due to the HX3D processor's surface texture, no liquid metal can be used. Its weaker cooling makes this noticeable, as the SCAR 17 with the normal Ryzen 9 7945HX has a bit of an advantage when it comes to maximum CPU performance.
