About this deal

Max boost for AMD Ryzen processors is the maximum frequency achievable by a single core on the processor running a bursty single-threaded workload. Max boost will vary based on several factors, including, but not limited to: thermal paste; system cooling; motherboard design and BIOS; the latest AMD chipset driver; and the latest OS updates. GD-150.

While a higher TDP usually relates to higher performance, the inclusion of the added 3D V-cache means that the processor can access a larger pool of superfast cache memory, which is even more useful when gaming than just throwing raw power at the problem. With its own dedicated extra cache, there are fewer fetch operations to the PC's main memory, so the chip runs more efficiently, and potentially cooler under load. A cooler’s longevity is greatly affected by its build quality; for example, if the radiator is made of aluminum, the device will last far longer than one with inferior quality. Naturally, your cooler’s performance, noise levels, and cooling efficiency are all affected by its build quality. Both processors belong to the same generation (Zen 4) and offer some impressive specs, but they have some differences that set them apart from each other. Starting with the core count, the Ryzen 9 7900X3D has 12 cores and 24 threads, while the Ryzen 7 7800X3D has 8 cores and 16 threads. This gives the Ryzen 9 a clear advantage in multitasking and running resource-intensive applications.

The chipset drivers also include a component that improves performance by parking the chiplet without extra cache when Game Mode or Mixed Reality Mode is active. In effect, this shuts down the ‘standard’ CCD, thus constraining latency-sensitive workloads (like games) to the 3D V-Cache chiplet. This improves the cache hit rate and reduces high-latency communication between the two CCDs, resulting in faster performance for workloads that don’t need access to (or benefit from) all the cores. These numbers aren't reflected in our overall geometric mean listed above but provide further context. The Ryzen 9 7900X3D provides 13900K-beating performance in a broad range of titles, with results ranging from -1.7% to +22.2%. Despite the air’s resistance, these fans can do their cooling purpose because they are built to emphasize focused airflow at high static pressure. The fans are visually appealing because of their innovative design, which connects the blades with an outside ring made of the same semi-translucent plastic. This, together with the RGB LEDs, creates a stunning visual effect. In terms of core and thread count, both CPUs have 12 cores and 24 threads, which means they are both capable of handling demanding workloads such as video editing, 3D modeling, and other productivity tasks.

If the 7900X3D does drop in price after release it will make its value for money only go up. If that does happen you can be certain that we will cover it here. Frequently asked questions What is a 3D cache? So let’s get into it. Here is everything you need to know about the Ryzen 9 7900X vs 7900X3D. Ryzen 9 7900X vs 7900X3D – Specs Specs Consequently, The density of the fins is ideal at 15FPI. As a result, the radiator is effective even when challenged by less airflow. The Eisbaer Pro Aurora is nearly completely made of practical water-cooling components. This cooler’s sturdy and long-lasting TPV hoses are often used in corporate products such as servers and workstations. The hose connections are likewise from Alphacool’s Enterprise line and are “ G1/4” in size. Ultimately, the reduced memory latency means that you're getting a chip that runs cooler, draws less power, and performs better thanks to the addition of the second generation of AMD's V-cache.Problem 2 - The Design: Due to the design of the chip only having the 3D v-cache on one of the two CCDs, core parking during gaming workloads is applied, meaning 6 cores and 6 threads are deactivated so you're only utilising the 6 cores and 6 threads that hold the 3D v-cache while gaming. When the 7800X3D launches that CPU only have 1 CCD which holds all the 3D v-cache meaning all 8 cores will be available during gaming. The Ryzen 9 7900X3D and Ryzen 9 7900X are both high-end desktop processors from AMD, both based on the Zen 4 architecture and manufactured on the TSCM 5nm process node. As you can see in the table above, the Ryzen 9 7900X3D's 3D V-Cache equipped chiplet actually has more cache-per-core than the 7950X3D, with 16 MB-per-core for the 7900X3D and 12 MB-per-core for the 7950X3D. It also has more L3 cache-per-core on the normal die, too. In contrast, AMD disables L2 cache slices in tandem with the cores, so the 7900X3D has 12 MB of L2 while the 7950X3D has 16 MB.

If you’re looking at an Alphacool product, you can probably guess it will be a performance powerhouse. Eisbaer’s latest AIO CPU cooler, the Pro Aurora, is the product line’s natural progression. Alphacool has developed the Eisbaer Pro Aurora CPU AIO water cooler for CPUs with massive CPU dies.Tech4Gamers has been around for 12 years, and throughout that time, it has established itself as a go-to resource for reliable information on all things technological.
