CPU Latest news

AMD Ryzen 7 4700G Renoir with Vega 8 GPU almost as fast as discrete entry-level graphics card, thanks to Overclocking

For the AMD Ryzen 7 4700G Renoir APU, new benchmarks have been leaked that could reveal their performance in various benchmarks. These latest benchmarks come from Chiphell, where a forum member was able to get a sample of the aforementioned APU and test it under various performance metrics, including graphics performance, of course. The tested APU is an Engineering Sample (ES) with the OPN code 100-1000000149.

However, this should still be an earlier pattern that does not yet have the final clock rates and therefore runs at 3.0 GHz base clock and 4.0 GHz boost clock. The Ryzen 7 4700G and the Ryzen 7 PRO 4750G would officially have final clock rates of 3.6 GHz base clock and 4.45 GHz boost clock. This means of course that the sample used by the Leaker is not yet what we can expect from the final models.

The tests were performed on an AORUS B550I PRO AX motherboard with two 8GB DDR4 memory modules. There’s no type mentioned, but these DDR4 DIMMs were clocked at 4300 MHz with an Infinity Fabric Link speed of 2100 MHz. We have already seen FCLK of up to 2200 MHz (DDR4-4400 MHz) in other benchmarks, so this once again points to the early stepping of the sample. The AMD Ryzen 7 4700G APU was overclocked to 4.3 GHz across all cores, an increase of 300 MHz over the standard operating boost clock of 4.0 GHz (single core).

According to the Leaker, both a 240mm AIO compact water cooling unit in an ITX case as well as a Noctua NH-D15 air cooler including liquid metal thermal compound were used for cooling. Both are already high-end cooling solutions, even for such an 8-core APU, so that the coolers as such should not be a limitation. The user reports that in order to reach the 4.3 GHz, he had to increase the voltage to 1.34 V (CPU-z is supposed to indicate a wrong voltage). In the stress test, the CPU reached a maximum temperature of 76 °C across all cores. The user also reports that this Renoir APU gets slightly hotter than a normal Ryzen 7 3800X, which could be due to the monolithic design.

More interesting later, however, are the performance benchmarks that were performed at 4.15 GHz (1.27 V) across all 8 cores. But first we’ll take a look at the AIDA64 results, where the CPU part including 4.3 GHz and DDR4 4300 MHz overclocking has a latency of about 62.8 ns and achieved respectable bandwidth results for the storage. This is not as much as what we have seen with other leaks, but it confirms once again that the final retail CPUs will certainly do much better than this early ES.

In Cinebench R15 the APU scores 2079 points in the multicore test, while in Cinebench R20 it scores 4789 points in the multicore test. Despite a slightly lower clock frequency and the early stepping of this chip, this is about the same level as a Ryzen 7 3800X at the same benchmarks. Further tests include the SuperPI (1M) run, which the chip was able to finish in 9.938 seconds, and finally there is the CPU-z benchmark, in which the AMD Ryzen 7 4700G achieved 507.8 points in the single-core and 5621.2 points in the multi-core benchmark.

Compared to an Intel Core i9-9900KF running at about 5.0 GHz, the ES of the Renoir APU was able to deliver about 5 percent better multi-threaded performance, with the Intel Core i9-9900KF performing about 5 percent better in the single-core tests. was up 6 percent. On this basis, the final retail chip should also easily surpass the Core i9-9900KF and the Core i7-10700K in the single-core performance figures.

The Leaker also tested the graphics capabilities of the Vega 8 GPU of the Ryzen 7 4700G APU and found that, all in all, it is a very powerful graphics solution. On the ES chip, the Vega 8 GPU ran at 1.7 GHz instead of the final clock frequency of 2.1 GHz. To accommodate this, he overclocked the GPU to a whopping 2.4 GHz with DDR4 memory at 4200 MHz. Unfortunately, there are no longer any pictorial evidence for this, but only a mention of the results.

According to this, the AMD Ryzen 7 4700G APU achieved about 5100 points in the 3DMark Firestrike and about 2700 points in the 3DMark Firestrike Extreme benchmark. Again, the benchmark results are not based on the final APU or the final launch drivers, so one should assume that the performance could be a bit higher.
