Why the new AMD Ryzen 7000 processors for the AM5 socket are currently not a good deal
Posted by Stefan on 2022-10-11
At the end of September 2022, the time had come: AMD presented its latest desktop processors called AMD Ryzen 7000. Initially, 4 processors with 6 to 16 CPU cores were released.
The new socket AM5 (LGA 1718) is used for the first time, which is intended to replace the very durable socket AM4 introduced in 2017 as AMDs mainstream platform. This includes (depending on the chipset) PCIe 5.0 support as well as the exclusive use of DDR5 memory on all AM5 mainboards.
Officially, DDR5-5200 is the maximum, but with AMDs EXPO Technology which is similar to Intel's XMP 3.0, AMD now also has a solution for easy overclocking of the main memory. AMD itself names DDR5-6000 as the sweet spot for the new AMD Ryzen 7000 processors.

The evolution of AMD Ryzen processors
Posted by Stefan on 2022-09-06
The AMD Ryzen processors are designed for the mid to high-end range and are grouped into the Ryzen 3, Ryzen 5, Ryzen 7 and Ryzen 9 classes. AMD follows the market leader Intel, which groups its Core i series (Intel Core i3, Core i5, Core i7 and Core i9) identically.
The AMD Ryzen processors were first introduced by AMD in Q1 2017. They are the successor to the not particularly successful AMD Bulldozer processors. The latter were manufactured using an outdated manufacturing process and could not keep up with the competing products from Intel. AMD lost a large portion of its desktop processor market share during this period.

First Geekbench 5 benchmark of the Intel Core i7-13700K
Posted by Stefan on 2022-07-26
Last week we already reported on the new Intel Core i7-13700K processor from Intel, which is expected in autumn 2022. With 8+8 CPU cores (24 threads), the Intel Core i7-13700K should have the same configuration as last year's Intel Core i9-12900K. With this, Intel wants to finally clear AMD's lead in multi-core performance, which has existed for several years.
AMD Ryzen 5 7600X and AMD Ryzen 7 7800X are coming in September
Posted by Stefan on 2022-06-20
After we published a performance assessment of the AMD Ryzen 9 7950X last week, the well-known AMD leaker Greymon55 has now posted more informations via Twitter.
He predicts the first four models of the new Zen 4 desktop generation, which AMD would like to present at the end of 2022. There is also an alleged release date of September 15, 2022.

Intel Core i9-13900 benchmark of engineering sample
Posted by Stefan on 2022-06-15
Intels 13th generation of the Intel Core i series (Raptor Lake) is about to be released and a lot of information is already known from the official side. This information includes e.g. the number of CPU cores, the expected increase in performance and the manufacturing technology of the new CPUs.
We compare the technical data of the Intel Core i9-13900 with its predecessor and look at benchmarks that have already been published.

Comparison of the two processors
The two processors from this comparison belong to the highest class of consumer processors. The Intel Core i9-12900K came on the market in the fourth quarter of 2021 and is based on the Alder Lake S architecture. This CPU is still manufactured using the 10 nanometer process and belongs to the 12 generation of Intel's I processor series. The AMD Ryzen 9 5950X came onto the market in the fourth quarter of 2020, but was already manufactured there using the 7 nanometer process. The AMD processor is based on the Zen 3 architecture with the code name Vermeer and, like the Intel Core i9-12900K, is designed as a desktop processor.The Intel Core i9-12900K has a total of 16 cores, which are divided into 8 high-performance cores (Golden Cove) with hyperthreading and 8 energy-saving cores (Gracemount) without hyperthreading. The base clock frequency is 3.20 gigahertz and the maximum turbo clock is 5.20 gigahertz. The AMD Ryzen 9 5950X also has 16 cores, but they are all equally potent and support hyperthreading technology. The standard clock is 3.40 gigahertz and the maximum turbo clock is 4.90 gigahertz.
In our benchmarks, the Intel Core i9-12900K scores around 10-15% better with single core load. Due to the 16 equally strong cores, the AMD Ryzen 9 5950X clearly catches up in the multicore benchmarks and is only slightly behind the Intel Core i9-12900K here.
The internal graphics unit Intel UHD Graphics 770 is built into the Intel Core i9-12900K, which clocks at up to 1.45 gigahertz and is equipped with 32 execution units and 256 shader units. This iGPU achieves an FP32 processing power (single precision) of 742 gigaflops. With the AMD Ryzen 9 5950X you have to do without an internal graphics unit and instead use a dedicated graphics card.
Both processors support DDR4-3200 RAM and the Intel processor also supports DDR5-4800 memory modules.
