AMD recently introduced the Ryzen 4000 Series APUs, a new generation that marks a significant leap and that has in the Ryzen 7 4700G its maximum exponent for the general consumer market.
The Ryzen 7 4700G has a Zen 2 CPU of 8 cores and 16 threads operating at a frequency of 3.6 GHz-4.4 GHz, normal and turbo mode, it has 12 MB of cache and it has an integrated Radeon Vega 8 GPU of the latest generation, manufactured in 7nm process and accompanied by 512 shaders at a maximum frequency of 2,100 MHz.
This type of integrated graphics solutions use system memory and use it as graphic memory, which means that the bandwidth and the data bus will depend on the configuration we have. The ideal, to maximize performance, is to have two 8GB modules (16GB total) installed on dual channel (128-bit bus) and with a frequency of at least 3,666 MHz.
The Ryzen 7 4700G beats PS4 and makes it possible, at last, to play in 1080p with an integrated GPU
The biggest advance that the Ryzen 7 4700G APU presents is in the CPU, of that there is no doubt. AMD has doubled the number of cores and threads compared to the previous generation, and CPI has risen up to the level of Intel Core processors.
The GPU has received minor improvements, but enough to seamlessly outperform the GPU that integrates PS4. To give you an idea of the importance of the different elements that make up a GPU, I leave you a simple comparison of the configuration of that Radeon Vega 8, present in the APU Ryzen 7 4700G, and the PS4 GPU.
Radeon Vega 8: 512 shaders, 32 texturing units, 8 raster units and a frequency of up to 2,000 MHz (latest generation GCN architecture).
PS4 GPU: 1,152 shaders, 72 texturing units, 32 raster units and a frequency of 800 MHz (GCN 2.0 architecture).
In terms of gross power, the Radeon Vega 8 GPU reaches 2.15 TFLOPs, figure that easily exceeds the 1.84 TFLOPs from the PS4 graphics core, and it is also imposed without problems on Xbox One, whose GPU barely reaches 1.41 TFLOPs. If we add the CPU to the equation the difference is enormous, since the Jaguar chip of both consoles is around 0.1 TFLOPswhile the Zen 2 CPU of the Ryzen 7 4700G APU reaches the 1.1 TFLOPs.
The numbers look good on paper, but we already know that unified memory architecture Using PS4 and Xbox One represents a clear advantage over the shared memory system used by APUs, and it can end up weighing heavily on performance. From TechEpiphany they have made an interesting comparison to see how it really positions that APU, and the results speak for themselves, it is capable of moving games in 1080p with medium or even high qualities without problems.
We can draw a simple and clear conclusion, the Ryzen 7 4700G is not only more powerful than PS4 and than Xbox One on paper, so is it in practice despite the limitations of shared memory (RAM and VRAM). Keep in mind, though, that 4,133 MHz RAM has been used in this performance test.
