Benchmark leaks are no longer reliable. The names of Ryzen processors turned out to be easy to spoof

It’s no secret that benchmarks can be cheated, and this week we found another way. It turns out that AMD Ryzen processors can be easily renamed, thus giving the test results of a more powerful chip to the results of a younger one.

It all started with Geekbench’s benchmark database finding test results for Ryzen 7000 processors that have not yet been presented, which looked quite likely and were widely scattered in specialized media; we also had material on this topic. In the end, it turned out that this was all a hoax organized by the website Chips and Cheese to show why this “leak” should not be trusted.

The PMCReader utility allows you to release processors one after the other. As Chips and Cheese explains, modern AMD processors have six CPUID write registers. With the help of the specified utility, these registers can be easily changed (up to 48 characters are entered) by firing the processor one after the other.

Here’s how the Core i9-13900K can be slower than the Core i9-12900K in a single-threaded test

Registers are usually written during processor startup. Applications like Geekbench, CPU-Z, AIDA64, etc. only check these registers to identify the processor and display the scan result in system information. At the same time, the rest of the specifications are shown quite correctly. However, there are applications that use other mechanisms and will not work. These are HWiNFO and BenchMate in particular.

Same fake Ryzen 7 7800X

With the help of the utility, you can get a funny or unusual CPU name, for example 3DNEWS, and quite possibly, as happened this week. The author of Chips and Cheese renamed the flagship Ryzen 9 7950X to Ryzen 7 7800X, disabled six of the sixteen cores and reduced the frequency, after which the resulting “new product” was tested on Geekbench. After that, a screenshot of the test result of the 10-core Ryzen 7 7800X, which AMD is allegedly preparing for release, began to spread on the Internet. And many believed this leak.

The processor became a popular meme

So now it has become even more difficult to trust the leaks with tests of certain processors that have not been introduced yet. It could very well be that we have a hoax made just for fun.
