The AMD RX 7600S Review
After recently introducing RDNA 3-based desktop graphics cards to users, AMD has now turned its focus to mobile GPUs. The Radeon RX7600S, RX7700S, RX7600M and RX7600M XT models, which were introduced about four months ago, are expected to hit the market soon.
Now the entry-level member of the family, the AMD RX7600S has been reviewed, So what features does the new GPU offer against the mobile RTX 4060? Here are the first results:
Rivals RTX 4060 in Laptops
The AMD RX7600S model comes with a 128-bit memory bus, 8GB of VRAM, 28 Compute Units, a 1792 Shader Processor and a Navi 33 GPU limited to X8 PCIe Gen4.
The new report shared by Computerbase benchmarks the RX7600S and RTX 4060 Max Q version. The RTX 4060 test system comes with a TGP of 140W, while on the RX 7600S this ranges from 83 to 88W. Interestingly, both cards have clock speeds higher than 2.4 GHz: 2612 MHz for RTX and 2446 MHz for RX.
What Do 3DMark Test Results Say?
According to 3DMark tests, with a TDP of 70W, both GPUs offer similar performance without ray tracing. But once the TDP goes up to 80W, the results change. While the RX7600S lags 6 to 13 percent behind its competitor in this case, it underperforms by half in the ray tracing test.
Two GPUs Compete in Low-Power Laptops
According to the shared information, it can be said that both GPUs will compete in low-power laptop solutions. However, when it comes to ray tracing, it should not be overlooked that the performance difference is widened. At this point, ComputerBase states that the preferred 8GB VRAM capacity for the RX7600S is a big bottleneck.
Clear Difference in Ray Tracing Performance
In reviews by Computerbase, the ray tracing performance of the RX 7600S is significantly lower than the RTX 4060. This may lead users to opt for the RTX 4060 when it comes to games and applications with high expectations for ray tracing technology.
Price and Performance Balance
Although the RX 7600S lags behind the RTX 4060 in terms of ray tracing performance, this new GPU is considered to be quite competitive in terms of price and performance balance. It is stated that the price difference between the two GPUs can compensate for the performance difference. This will be an important factor, especially for budget-friendly laptops.
At the start only Navi 33, because Navi 32 is not finished yet
Four different graphics models based on Navi 33 will come into the notebook. The Radeon RX 7600 is available three times as the Radeon RX 7600M, Radeon RX 7600M XT and as the energy-saving Radeon RX 7600S, while the Radeon RX 7700S remains the only model with the bigger name. Variants with more power should still be a long time coming. Just like Nvidia’s flagship AD102 GPU, the Navi 31 GPU will not find its way into the notebook and Navi 32 as AMD’s interim solution is not ready yet.
In the middle class and in the high-end segment, AMD has to let the competitor with the GeForce RTX 4000 laptop GPUs go for the time being. Because the OEMs are currently relaunching their (gaming) notebooks with Intel’s mobile 13th generation Core or the AMD Ryzen 7000 Mobile presented at the same time, AMD should have a particularly difficult time this year with mobile GPUs in terms of design wins.
Navi 33 differs significantly from Navi 31
All the details about the new Navi 33 GPU are not yet known, but there are massive differences to the big Navi 31. It is a monolithic (one chip) GPU manufactured in the 6 nm process at TSMC, which with a size of 204 mm² is quite small. The predecessor Navi 23 was still 237 mm². It is still unclear to what extent there have been changes to the FP32 units, the cache system, the infinity fabric and other properties of RDNA 3 compared to Navi 31.
