Which to select
It is time to pick the winner. What is the difference between AMD Phenom II X3 B77 vs AMD Epyc 7642? What CPU is more powerful? It is quite easy to determine – look at comparison table. The processor with more cores/ threads and also with higher frequency is the absolute winner!
CPU Cores and Base Frequency
Who will win between AMD Phenom II X3 B77 vs AMD Epyc 7642. The general performance of a CPU can easily be determined based on the number of its cores and the thread count, as well as the base frequency and Turbo frequency. The more GHz and cores a CPU has, the better. Please note that high technical specs require using a powerful cooling system.
CPU generation and family
Some manufacturers complement their CPUs with graphic chips, such a solution being especially popular in laptops. The higher the clock frequency of a GPU is and the bigger its memory, the better. Find a winner - AMD Phenom II X3 B77 vs AMD Epyc 7642.
Hardware codec support
Here we deal with specs that are used by some CPU manufacturers. These numbers are mainly technical and can be neglected for the purpose of the comparison analysis.
Memory & PCIe
These are memory standards supported by CPUs. The higher such standards, the better a CPU’s performance is.
Data encryption support
Memory & AMP; PCIe
The thermal design power (TDP), sometimes called thermal design point, is the maximum amount of heat generated by a computer chip or component (often a CPU, GPU or system on a chip) that the cooling system in a computer is designed to dissipate under any workload.
Devices using this processor
You probably know already what devices use CPUs. These can be a desktop or a laptop.
It is the updated version of the Cinebench R15 benchmark. This version provides improved benchmark accuracy at testing of processors. Cinebench R20 is based on Cinema 4 Suite. It is the software used to create 3D forms. The benchmark runs for single-core test procedure without counting of hyperthreading ability.
It is the updated version of Cinebench 11.5. As all new versions, the updated benchmark is based on Cinema 4 Suite software. The latter is used for creation of 3D models and forms. Cinebench R15 is used for single-core processor performance benchmark test. The hyperthreading ability doesn't count.
This benchmark is the updated version of the Cinebench 11.5 which is based on Cinema 4 Suite soft (it is widely used for 3D production). Cinebench R15 can be used for multi-core processor performance benchmark testing. The test produces precise and accurate results.
Geekbench 3 is the benchmark for Intel and AMD 64-bit processors. It employs a new power estimation system for a single CPU core. This software carries out the modeling of real scenarios to provide accurate results. The better the estimation, the faster your computer works.
Geekbench 3 benchmark supports AMD and Intel multi-core processors. Being based on MAXON CINEMA 4D, it allows obtaining the real comparative CPU potential. The higher the indicator, the more powerful and fast the processor is.
This synthetic test will help you determine the real computing power of a single core in the central processing unit. Cinebench R11.5 is based on MAXON CINEMA 4D and employs various testing scenarios and branded power analysis algorithms. The higher the estimated value, the faster the computations of a single CPU core are.
Cinebench R11.5 carries out simultaneous cross-platform tests on all the processor’s cores. By running realistic 3D scenes, this benchmark will reveal all the potential of your Intel or AMD single-unit processor. The winner is quite easy to identify - the higher the estimation, the faster the CPU is.
PassMark is one of the most popular benchmark in the world. It tests entire and overall performance of the central processing unit (mathematical calculations, compression and decompression speed, 2D&3D graphic tests). Below you will see benchmark testing results for the processor and its score. Please note that data can differ from the real-world situations.
