Zen 3 ram speed9/14/2023 ![]() ![]() With Zen 2 EPYC, the CCDs could sit right near each other, as the IF were coming down from the middle:īut with the new layout, that will not be possible anymore.We know that selecting the right memory for your PC can be overwhelming, with various factors to consider. It will be interesting to see how this is arranged on the EPYC / Threadripper, with the asymmetrical CCD. ![]() (Probably also how they managed to improve power efficiency, the X-bar is (much) wider and lower clocked, so consumes less power) The length of the links themselves is most likely reduced by 30-40% !!Īnd by the way his picture looks, there's a big-ass wide crossbar right in the middle of the die, that seems a very VERY wide bus ! ![]() Zen 3 ( I/O is on one of the sides, most likely towards the I/O die ) The IF had to travel from the middle UNDER half of the cache, and then converge on the I/O die: Zen 2 ( all the I/O is smack in the middle, with cores on the sides) If the new CCDs have a better structure (for example, with the IF portion on the side instead of in the center, the IF links themselves may be a few millimetres shorter), allowing for that little bit of extra speed. however, that was done with 2:1 ratio (memory:IF), because IF on Zen2 doesn't scale beyond 1900 Mhz, that's about the max. I/O die was already capable of much faster memory speeds, plenty of overclockers went beyond DDR4-5000 (2500Mhz). The series is a is 27in IPS-type 2560 x 1440 monitor with thin panel border and very slim hard outer bezel component.

A newly spotted trademark entry shows or at least seems to indicate that Big Navi would get Infinity Cache.Īerocool Mirage 5 is a cylindrical air CPU cooler with Infinity Mirror RGB - 08:43 AMĪerocool announced a the cylindrical CPU cooler called Mirage 5, fitted with an Infinity Mirror RGB illumination function. The new optimum, however, is DDR4-4000 with a synchronous IF or fabric clock (FCLK) and memory controller clock (ULCK) of 2,000 MHz.ĪMD Big Navi would get Infinity Cache - 11:35 AM Thus, users will be able to reach higher frequencies and make fine adjustments.ĭDR4-3600 remains the "sweet spot" and AMD's recommendation for the Zen 3-based processors, which are also specified with up to DDR4-3200. Memory Clock (mclk) : Frequency of main system memory.Īs a result, RAMs will work more stable with new generation Ryzen processors.Memory Controller Clock (uclk) : Manages how fast the memory controller can receive / transfer commands from RAM.Infinity Fabric Clock (fclk) : Manages how fast CPU cores can communicate with CPU components and SoC controllers.The memory controller used by AMD and Infinity Fabric management, which manages the components within the CPU, is very important. Memory management in AMD Ryzen processors is divided into three basic elements. Since ddr4-4000 has an actual clock speed of 2,000 MHz, that means that that speed can in all probability be (reasonably) achievable. That speed was relevant with the Zen 2 chips because it was generally the highest possible memory speed with the infinity fabric in 1: 1 mode. This also seems to be the case for Ryzen 5000: according to the slide, memory and fabric clock is the most cost-effective method for tinkering with the chips. The slide claims that ddr4-4000 is to Ryzen 5000 what ddr4-3800 was to Ryzen 3000. A leaked slide shows that the upcoming Ryzen 5000 chips should be able to achieve higher infinity fabric clock speeds compared to their predecessors. ![]()
