The Ryzen 9 3900X is here! It’s not the most powerful of the bunch – it hasn’t been since the Ryzen 9 3950X with 16 cores – but the Ryzen 9 3900X is still a formidable 12-core/24 thread multithreaded powerhouse. Amd Ryzen 9 3900X Black Friday Deals 2021 This chip, which is based on the Zen 2 architecture has helped Intel close the gap after years of being behind. With its new CPU architecture, AMD finally gained the process advantage over Intel. AMD’s 7nm client launch efforts are not restricted to processors. On July 7, AMD also launched the RDNA GPU architecture, the RX 5700-series (formerly known as AMD Navi). Two new graphics cards, Radeon RX5700 XT (and RX5700) were released to compete with Nvidia’s Super lineup. The Ryzen 9 3900X is the first name we have put under the microscope.
The 24-thread, 12-core processor is the fastest and most powerful chip in the red team’s Zen architecture. It costs $499, with an RGB cooler. Although this is a major change in chip design and will not support older 3rd Gen Ryzen processors, most 400-series AM4 motherboards as well as 300-series AM4 motherboards, it will still work with the new chipset. The brand-new chipset can also unlock full PCIe4.0 bandwidth. It can drive twice the bandwidth between your chip and storage as well as I/O devices, compared to today’s PCIe 3.0 standard. SPECIFICATIONS BENCHMARKS PERFORMANCE VERDICT AMD Ryzen9 3900X specs AMD RYZEN9 3900X SPECS Zen 2’s architecture uses the 7nm process. It also incorporates a mixed-node chiplet. The red team now has a new balance of power and performance, which is evident today with the Ryzen 93900X.

The Ryzen 9 3900X, which can boot at speeds up to 4.6GHz and 3.8GHz, is currently the fastest 3rd-gen Ryzen chip. The Ryzen 9 3900X will replace it in September. At that point, the 16-core Ryzen 9 3395X will be the dominant chip. It is still the dominant processor, providing a lot of performance for heavy-duty multitasking and gaming. This is largely due to the Zen 2 architecture, which acts as the backbone of AMD’s Ryzen 3000 processors’ performance improvements. AMD is known for being innovative and able to challenge its rivals. This time, it created a design that makes use of its Infinity Fabric between one 14nm I/O (cIOD), and one or two 7nm chipslets (CCD). Ryzen 9 3900X has two 8-core CPUs. Each CCD is slightly slower than the other to reach the 12-core/24-thread total count. AMD Zen 2 has a 15% increase in Instruction per clock (IPC).
This was possible through numerous upgrades and streamlining efforts across branch prediction and cache, integer execution, and floating-point. This updated core complex was designed in the same way as its predecessor. It has large banks of L3 cache sandwiched between L2 and a separate core on each end. Ryzen9 3950X Ryzen7 3800X Ryzen7 3700X Ryzen5 3600X Ryzen5 3600X Ryzen5 3600X Ryzen5 3600X Ryzen5 3600 Cores/threads 16/32 8/16 8/16 8/16 Turbo clock 4.7GHz 6/12 6/12 3900X which has the same L3 cache at 64MB. There have been significant upgrades to the CCX and the memory controller on the cord. The first Ryzen generation’s memory compatibility issues were a problem, but the new third-gen units have made efforts to fix it. The interconnecting Infinity Fabric has been removed from the memory controller between the cIOD/CCD.

This allows for greater memory capacities with 3rd Generation Ryzen. DDR4 above 4,200MHz is rated as “easy”, and even 5,133MHz kits can be considered. The sweet spot is between 3,600 and 3,733MHz. Uclk switches to a 2:1 Uclk/Flck ratio at this speed. This causes an increase in overall latency. AMD IS CONTINUING to RAMP UP THE PACE of CHANGE WITH ZEN 2. Below, we have chosen a 3,200MHz for the Ryzen9 3900X testing. While 3rd Generation Ryzen (and Intel’s chips) have some performance issues, overall, we can see a strong comparison between the Zen+, Coffee Lake, and Zen 2 architectures. The 7nm process node has helped to quench this chip’s power thirst. The Ryzen 9 3900X is within a 105W TD and requires 210 watts total platform energy under x264 v5.0 benchmarking. The 7nm process has a lower power consumption than the 8-core Ryzen 7 2270X, which is a sign that it’s paying off where it matters. It was a huge buildup to AMD’s launch party for Ryzen 3000 CPUs (aka Zen 2), which took place on April 8.
The Ryzen 3000 CPUs are the first mainstream CPUs that use a 7nm manufacturing process. AMD could win the title after flirting with the crown in the previous Ryzen generations. The Ryzen 9 3900X will be the best CPU for gaming and everything else. We are about to find out. I have already taken a deep dive into Zen 2 and Ryzen 3000 architectural updates. This is a 3,000-word primer for those who are interested. If you’re curious about the details behind the changes, then start here. This is the final score after the initial review. AMD has been updating firmware and I have tested the 3900X multiple times. This is a realistic representation of the performance you will get. While the Ryzen 9 3900X will be the focus, the 3700X (and 3600X) are included in the performance slides. Let’s begin with a high-level overview before we move on to the real-world results. It is quite difficult to summarize the changes made for Zen 2 architecture. Zen 2 includes an improved L2TAGE branch predictor, a larger macro-op cache, and doubles L3 cache size (to 32MB per CCX), as well as doubles AVX floating-point performance. A third address generation unit (AGU) is available. There are larger buffers (eg reorder buffer, integer scheduling, physical register file, queue, and many more), multiplication latency has been reduced to 3 cycles from 4, and 128-bit buses have been added to increase bandwidth.
PCIe Gen4 support is available, as well as changes to the Infinity Fabric, which links everything together. There are also improvements in memory compatibility. All of this is wrapped in a 7nm bow. The memory controller can be moved from the main CPU chipset to a secondary IO chipset. Both will then be stuck together into a single package. There are also options for dual CPU chiplets for higher-tier models such as the 3900X. This is the Ryzen 3000 family. It currently includes 6-core/12-thread Ryzen 5 3600 models that use a single CPU chipset with two CCXes. Up through the Ryzen 9 3900X, which has 12-cores and 24-threads distributed over two CPU chipsets. The Ryzen 9 3950X, which will have a 16-core/32 thread solution, will soon be available. I hope to be able to test one in the near future. This topology has obvious benefits. This topology has obvious benefits. Yields are lower than high-core count processors. Clock speeds are not tied to perfect or near-perfect dies. AMD Ryzen 9 3900X Black Friday Deals 2021 The Ryzen 9 3900X does not need to sacrifice speed for multicore performance. This chip is the “megatasker” champion right now. It’s also the single-threaded prizefighter taking on Intel on the gaming front.
