The first four versions of the Ryzen 7000 CPUs will be available on September 27, and AMD is using the same policy it used while launching the Ryzen 500 series. It's starting with four higher-end, higher-priced parts, while lower-end CPUs for prevailing and budget builds will follow next year.
| CPU | MDRP | CORES/ THREADS | CLOCKS (BASE/BOOST) | TOTAL CACHE (L2+L3) | TDP |
| Ryzen 5 7600X | $299.00 | 6c/12t | 4.7/5.3 GHz | 38MB (6+32) | 105W |
| Ryzen 7 7700X | $399.00 | 8c/16t | 4.5/5.4 GHz | 40MB (8+32) | 105W |
| Ryzen 9 7900X | $549.00 | 12c/24t | 4.5/5.6 GHz | 76MB (12+64) | 170W |
| Ryzen 9 7950X | $699.00 | 16c/32t | 4.5/5.7 GHz | 80MB (16+64) | 170W |
The other two chips are a little cheaper than their Ryzen 5000 counterparts; the 16-core Ryzen 9 7950X launches for $699, $100 less than the 5950X, while the 8-core Ryzen 7 7700X starts at $399, $50 less than the launch price for the Ryzen 7 5800X
Although AMD claimed that "optimizations" made throughout Zen 4's development have increased its instructions-per-clock (IPC) increase over Zen 3 to an average of 13 percent, up from the 8–10 percent increase the company said earlier this year.
Substantially, the maximum clock speed of the 7950X has already increased to 5.7 GHz, 800 MHz faster than the boost clock of the Ryzen 5950X and makes the 7950X an average of 29 percent more quickly than the 5950X at tasks that benefit from the execution of an entire task from beginning to end without interruption, including games.
Mark Papermaster, AMD Chief Technical Officer, says that Zen 4 is an alteration of the Zen 3 architecture that mainly targeted the "front end" of the architecture to more efficiently fetch and pass tasks along to the improved execution engine of Zen 3.
Additionally, most of Zen 4's 13 percent IPC boost comes from these optimizations, while branching prediction, a doubled L2 cache, load/store improvements, and other minor execution engine modification account for the rest.
Moreover, specific tasks like machine learning and AI workloads can also benefit from the introduction of AVX-512 extensions. It puts Intel in a strange spot where the company defined these extensions nearly a decade ago and was alone in pushing them for years.
But it has disabled AVX-512 support in its 12th-generation CPUs because the processors' efficiency cores don't support it. These extensions have been disputable because using them can consume a lot of power and the workloads that benefit from them are specialized and relatively rare.
Meanwhile, higher CPU efficiency is also suitable for mini-ITX systems, where you might not have the cooling capacity to let the CPU consume tons of power and generate tons of heat.
