Review: Ryzen R9 7950X, R9 7900X, R7 7700X and R5 7600X


The last word:

What about overclocking? And the gaming part?

Overclocking will be covered in the articles dedicated to motherboards. You can already read our complete article about the AORUS X670E Master by following this link. We have started our tests with the Ryzen 7950X to see if it still has something to offer. We are also preparing a file dedicated to the overclocking of these Ryzen 7000, in particular with the use of AMD Ryzen Master.

As far as gaming performance is concerned, we had to make the choice to postpone it in order to offer you qualitative results. The lack of time and the desire to do our best forced us to make you wait. But don’t worry, we’ll be back with an article dedicated to gaming, including a match between the Ryzen 5 5600X and 7600X against the i5-12600K! Our first impressions suggest that the Ryzen 5 7600X could be a very interesting choice thanks to its more attractive price, its lower power consumption than its bigger brothers and also a more contained temperature.

CPU AMD Ryzen 7000

The Ryzen 7000’s are up to the task!

Well, there’s no doubt about it, the performance of these Ryzen 7000s is good, with the Ryzen 9 7950X crushing the current competition in full-core benchmarks. One of the reasons for this is the increased frequency of these new processors compared to the previous generation. As a reminder, during our tests, on a benchmark using only one core, our Ryzen 9 7950X under custom watercooling saw its frequency maintained at 5825 MHz. We also did a series of tests where the 16 cores can stay at 5.4 GHz with correct temperatures for this type of CPU.

The whole range sees an improvement in performance, especially when using a single core. The addition of DDR5 is a real plus, although throughput could be even better as our AIDA64 tests show. AMD has done a good job of offering a 5nm processor with DDR5 support and an iGPU solution.


A cooling system that is up to the task!

Our tests confirm that a liquid cooling solution is mandatory, even for the Ryzen 7600X and 7700X where AMD recommends a tower type cooling unit. Personally, we can only advise you to opt for liquid cooling in order to fully benefit from the performance of your processor. Depending on the model, you will need to increase the size of the radiator. Even if AMD does not consider 90°C to be a problem, you will need an efficient solution to dissipate this heat, especially in a case.


Performance, yes, but at what price ?

Behind this title is a double issue. First of all, the price of this new range of processors that we don’t know exactly yet. No doubt the conversion will be bad for European buyers as the dollar is particularly strong at this time. We’ll have to wait for the processors to be in stock in the shops to see what price they will be offered at. We’ll be sure to write about it in a future issue.

In this period where we fear power cuts in the next few weeks, we can’t ignore the power consumption of these Ryzen 7000. If we don’t have to complain about the Ryzen 7600X and 7700X, the 7950X’s power consumption is exploding, despite its 5nm engraving. The high frequencies and the voltage that follows lead to a large increase in consumption compared to the previous generation with the 5950X. This observation will lead us to propose to you in the next few weeks ways to lower the power consumption without losing too much performance, as well as to tell you about the AMD Eco Mode.


The AMD ZEN 4 architecture

Frankly, we encountered very few problems during our week of testing. Admittedly, there are still a few bugs in terms of the BIOS, especially in relation to memory, but this is quite logical. The performance is there straight away without any changes in the BIOS. It is sometimes the startup that has been more recalcitrant, but this is due to the memory. No doubt that the next few weeks will see new updates that will correct these small launch problems.

As you can see, we are quite satisfied with this new generation proposed by AMD and its X670E chipset. Now, we should also find some very interesting models built around the B650E. The next few weeks will see a new duel between this new generation of AMD processors and Intel Raptor Lake. With that in mind, we’ll see you tomorrow and this week to find out more about the ROG Crosshair X670E Gene, the ROG Crosshair X670E Extreme and the AORUS X670E Xtreme motherboards.
