AMD Ryzen 7000 “Zen 4” Desktop CPUs Official - Full Specifications, Performance & Pricing Unveiled
The unveil today covers several aspects that users were waiting for. We had already learned the specifications earlier this month but now we get to confirm that they were indeed correct and we can also take a look at the official performance numbers and the prices from AMD itself. But before we get into that, let’s take a look at the CPUs that we will be getting during launch:
AMD Ryzen 9 7950X - $699 US AMD Ryzen 9 7900X - $549 US AMD Ryzen 7 7700X - $399 US AMD Ryzen 5 7600X - $299 US
So before getting into the core specifications of these four SKUs, we have to point out that the AMD Ryzen 7000 CPUs are based on a TSMC 5nm process node with a CCD die size of 70mm2 compared to 83mm2 for Zen 3 and featuring a total of 6.57 Billion transistors, a 58% increase over the Zen 3 CCD with 4.15 Billion transistors, The CPUs adopt the Zen 4 architecture, bringing with it a 13% IPC uplift but the majority of the performance benefit comes from the higher clock speeds and a higher TDP that is supplemented to each chip versus the prior generation. At the top of the stack, the 16-core AMD Ryzen 9 7950X processor offers up to 57% better content creation performance in V-Ray Render compared to the competition. Meanwhile, even the 6-core AMD Ryzen 5 7600X processor offers an average of 5% faster gaming performance across select titles than the competitor’s flagship gaming processor. The incredible performance improvements also come with stunning advances in energy efficiency; AMD Ryzen 7950X processor is up to 47% more energy efficient than the competition. Beyond the core, the Ryzen 7000 Series Processors feature an all-new 6nm I/O die, which enables hardware-accelerated video encoding/decoding, light-duty graphics work, and multi-display support. Across the CPU, a host of new power management technologies leveraged from AMD’s ultra-efficient mobile processors allow Ryzen 7000 Series Desktop processors to run more efficiently than ever before. Ryzen 7000 Series Desktop processors are expected to be available globally from leading etailers and retailers beginning September 27, starting at a SEP of $299 USD. AMD has highlighted a +29% Single-Threaded, >35% Multi-Threaded and >25% Perf/Watt increases when comparing Zen 4 to Zen 3 cores. The IOD is fabricated on the 6nm process node and houses an iGPU which comes with 2 RDNA 2 Compute Units running at up to 2200 MHz as detailed here. It features a die size of 124.7mm2 which is almost the same size as the Zen 3 IOD which measured at 124.9mm2. AMD Ryzen 7000 Desktop CPU Render (With/Without IHS): As per AMD, the main improvements for IPC come from a new Front End & Load/Store + Branch Predictor that makes up for 80% of the gains while the L2 cache structuring and Execution Engines offer the remaining 20% uplifts. AMD also highlighted that AVX-512 & VNNI add up to 30% faster FP32 (multi-thread) inferencing performance and a 2.5x gain in INT8 (multi-thread) CPU performance uplift. In addition to the larger caches, the Micro-op cache has been increased from 4 KB to 6.75 KB, the L1I and L1D cache stick to 32 KB, the L2 cache size has doubled to 1 MB and now runs at 14 cycles instead of 12 while the L3 cache also features slightly higher latency, going up from 46 cycles to 50 cycles. The L1 BTB has also been increased from 1 KB to 1.5 KB. Compared to Zen 3, Zen 4 architecture is also going to be really efficient, offering 62% lower power at the same performance, and 49% more performance at the same power. The CPUs also feature 50% less area versus the competition (10nmESF Alder Lake) thanks to their 5nm process node and up to 47% higher power efficiency. AMD Ryzen ‘Zen 4’ Desktop CPU Features:
Up To 16 Zen 4 Cores and 32 Threads +29% Performance Uplift In Single-Threaded Apps Brand New Zen 4 CPU Cores (IPC / Architectural Improvements) Brand New TSMC 5nm process node with 6nm IOD >25% Performance Per Watt Improvement Vs Zen 3 >35% Overall Performance Improvement Vs Zen 3 ~13% Instructions Per Clock (IPC) Improvement Vs Zen 3 Support on AM5 Platform With LGA1718 Socket New X670E, X670, B650E, B650 Motherboards Dual-Channel DDR5 Memory Support Up To DDR5-5200 Native (JEDEC) Speeds 28 PCIe Lanes (CPU Exclusive) 105-170W TDPs (230W PPT)
The CPUs will come with an optimized cache restructuring, featuring double the L2 cache (1 MB vs 512 KB), a shared L3 cache like the previous generation, support for DDR5 memory with EXPO (AMD’s Extended Profiles For Memory Overclocking), PCIe Gen 5.0 graphics card, and M.2 SSD support. Overclocking features such as PBO and XFR will also carry over from the past chips. So with all of that said, let’s get on with the specifications. AMD Ryzen 7000 CPU Box Packages:
AMD Ryzen 9 7950X 16 Core “Zen 4” Desktop CPU
Starting with the flagship of them all, we have the AMD Ryzen 9 7950X which retains its healthy 16 core and 32 thread count from the previous two generations. The CPU will feature an impressive base frequency of 4.5 GHz and a boost clock of up to 5.7 GHz (5.85 GHz F-Max) which should make it 200 MHz faster than Intel’s Alder Lake Core i9-12900KS which has a boost frequency of 5.5 GHz on a single-core. It looks like AMD is extracting every ounce of Hertz that it could within that 170W TDP (230W PPT) for the Ryzen 9 chips. As for the cache, the CPU comes with 80 MB of that which includes 64 MB from L3 (32 MB per CCD) and 16 MB from L2 (1 MB per core). The flagship is going to cost $699 US which means that it will be priced slightly higher than the Core i9-12900K while offering a significant performance leap in multi-threading apps such as Chaos V-Ray of up to +57% and doing so with up to 47% higher energy efficiency. In terms of gaming performance, the AMD Ryzen 9 7950X will be offering up to 35% higher uplift in games such as Shadow of The Tomb Raider versus the Core i9-12900K.
AMD also showcased the performance of the AMD Ryzen 9 7950X against the Intel Core i9-12900K in both gaming and content creation tasks. The CPU was anywhere from -1% to +23% faster in the gaming benchmarks and +36 to +62% faster in creation workloads.
AMD Ryzen 9 7900X 12 Core “Zen 4” Desktop CPU
Next up, we have another AMD Ryzen 9 chip, the 7900X, which as the name suggests, would come equipped with 12 cores and 24 threads. The CPU comes with an even higher base clock of 4.7 GHz and a boost clock adjusted at 5.6 GHz across a single core. The CPU retains its 170W TDP and gets 76 MB of cache (64 MB L3 + 12 MB L2). The CPU will be positioned in the same ballpark as the AMD Ryzen 9 5900X but with performance that would shake the ground from below the Core i7-12700K. The Ryzen 9 7900X will retain the same prices as the Ryzen 9 5900X while offering better processor capabilities.
AMD Ryzen 7 7700X 8 Core “Zen 4” Desktop CPU
Moving over to the Ryzen 7 family, here we have the AMD Ryzen 7 7700X, an 8-core and 16-thread part. AMD positions this as the sweet spot for gamers and as such, the CPU will feature a base clock of 4.5 GHz and a boost clock of 5.4 GHz but at a lower 105W TDP (142W PPT). The CPU will get a 40 MB cache pool which consists of 32 MB L3 from the singular CCD &8 MB L2 from the Zen 4 cores. Now one interesting thing to mention is that there is so far no update by AMD on a Ryzen 7 7800X chip. It is likely that AMD wants to replace that part with a successor to the Ryzen 7 5800X3D with Zen 4 cores (3D V-Cache). If that was the case, we can expect an update later this year to the CPU lineup since the V-Cache parts have been confirmed for a late Q4 2022 launch by AMD themselves. The Ryzen 7 7700X will be priced at $399 US and will be competing with the Core i7-12700K during launch.
AMD Ryzen 5 7600X 6 Core “Zen 4” Desktop CPU
Last up, we have the most budget-tier chip (if you can call it that but the pricing won’t be reflective of that), the Ryzen 5 7600X. This will be a 6-core and a 12-thread part that features a high 4.7 GHz base clock and a 5.3 GHz single-core boost frequency. The CPU will also run at a 105W TDP (142W PPT) which is much higher than its 65W predecessor though once again, that’s the sacrifice you’ve to pay to achieve the faster clock speeds. The CPU will carry 38 MB of cache that comes from 32 MB of L3 and 6 MB of L2 on the die. This chip is going to be priced at $299 US and will be offering a 5% performance gain over the Core i9-12900K in gaming. Based on the overall Single-Threaded performance increase in Geekbench 5, we can compile the following chart:

So while we got to see the official unveil today, we should also remember that the CPUs won’t hit retail shelves until a while later. The official sales date is planned for 27th September while the Ryzen 7000 CPUs will go on pre-order around two weeks earlier on the 15th of September.
