RDNA 4 vs Blackwell: Who from AMD or NVIDIA has progressed the most in pure performance with its new GPU architecture?

Our colleagues from Computerbase had an intriguing idea: to estimate the performance gain between the old. Consequently. However, new GPU architectures ofAMD et NVIDIAby limiting all possible parameters as much as possible so that the differences in results are only linked to these famous architectural differences in themselves. Similarly, More concretely. In addition. Furthermore, because said as it is hardly clear, their idea was to be able to compare two generations of GPU of the same brand comprising the same number of flow processors (shaders), by forcing the same operating frequencies of the GPU and the same memory bandwidth. Nevertheless, Thus. Therefore. Therefore, if there is a difference in performance, the logical conclusion will be that it is the architecture of these GPUs which is the cause. In addition. A well -known principle of measure rdna 4 vs blackwell: who new of the world of CPUs when we mention theIPC (Instructions rdna 4 vs blackwell: who per cycle). Similarly, but therefore adapted here to the world of GPUs. You may imagine. but the realization was not that simple. which will force you to read a little more to understand the results that will follow.

On the side of Nvidia. for the match Blackwell vs Ada Lovelaceour comrades have chosen to oppose the Geforce Rtx to the GeForce RTX. 4070 Ti SUPER. The first has 8960 Cuda Cores against 8448 Cuda Cores in the second. so it was necessary to compensate for this difference in shaders by playing on the frequencies: 2360 MHz for. the RTX 5070 Ti against 2500 MHz at the RTX 4070 Ti Super. They also had to do the best with the memory bandwidth. because the GDDR7 brings so much that even by putting it at least possible. by rdna 4 vs blackwell: who new pushing the GDDR6X on the contrary in its last entrenchments, they did not reach rdna 4 vs blackwell: who a draw with 864 GB/S for the RTX 5070 Ti against 784 GB/S for RTX 4070 Ti Super. However, this remains close, the impact on raised performance should therefore be quite negligible.

We go to AMD where things were not simple there too. The face-to-face RDNA 4 vs RDNA 3 is made with match Radeon RX 9060 XT 16 Go vs Radeon RX 7600 XT. For shaders, it’s perfect since the two cards have 2048 flow processors. On the other hand. it was greatly complicated to computebase when trying to put the same GPU frequencies since they simply did not succeed. They did what they could all the same so that the gap is limited to a hundred MHz. then had the idea of ​​a plan B: measure the average frequency of rdna 4 vs blackwell: who new each GPU. this during each test, and then take out the calculator and ultimately establish scores at equivalent rdna 4 vs blackwell: who frequency.

Now. these bases are explained. you have all the cards in hand to appreciate at its fair value “the work of the artist”. Those of you who follow the world of Hardware PC anyway. who have read our different tests of the GeForce RTX 50. Radeon RX 9000 on H&CO must suspect the result. We are not going to reveal everything. but here is an example the assessment obtained after the trials in rasterization 4H UHD:

In the full article in connection. below (in German. do not hesitate rdna 4 vs blackwell: who new to activate the translator of your internet browser). you will also have the results in Ray Tracing rdna 4 vs blackwell: who and even in path tracing, as well as the scores obtained under each game tested separately.
