Finally adding native PCIe 3.0 support in addition to native USB3 & 3.1 functionality. AMD Zen CPU & AM4 Socket Pictured - PGA Design With 1331 Pins ConfirmedĪM4 is a huge step-up from the aging AM3+ socket. Making it the first of its kind to offer compatibility with all of AMD's desktop products replacing AM & FM sockets and consolidating them into a single solution. AM4 will share cross-compatibility with upcoming Bristol Ridge APUs and the Summit Ridge family of high-end Zen CPUs. Confirming a return to the company's signature Pin Grid Array design with extensively expanded functionality. One thing seems fairly certain for now - AMD is working on Zen 4 to be a powerful lineup of CPUs capable of competing against Intel’s 13th-generation Raptor Lake processors.AMD's upcoming Zen processors and brand new unified "AM4" socket have been pictured. This means that many features may still change. The launch of AMD Zen 4 Raphael is still a long way away - the CPUs are likely to hit the shelves in late 2022. Some of the other likely upgrades include DDR5 memory support with base clock speeds starting at 4,800MHz and going up to 10,000MHz, PCIe 5.0 compatibility, and RDNA 2 onboard graphics. There will be more core counts in the future - I would not say those are the limits! It will come as we scale the rest of the system.” Lisa Su, the CEO of AMD, “We are focusing on Zen 4 and Zen 5 to be extremely competitive. This suggests an upgrade over the current 16 cores and 32 threads.Īccording to Dr. AMD has previously hinted that it hopes to increase the number of cores found in mainstream processors. Rumors point to the new Zen 4 architecture bringing up to 25% instructions per clock (IPC) gain over Zen 3, as well as a 5GHz clock speed. The switch to Zen 4 architecture should bring a host of improvements and exciting changes. We will have to wait and see how AMD addresses this potential issue. That could have some repercussions, such as the air being trapped in the central chamber or blown into the VRMs of the motherboard. If they are indeed cut-outs, it’s possible that AMD designed the socket to vent air out of it. The two partitions on each side of the socket could be cut-outs, but they could also just be reflections from the render. Much like the rest of the socket, the IHS resembles Intel solutions in its design, namely the Intel Core-X HEDT line of CPUs.Īs we only have renders to go on right now, some of the design choices are pure guesswork at this point. The size of the IHS implies that AMD may be trying to balance the temperatures and thermal load across several chiplets. Inside, the CPUs will house an unexpectedly large integrated heat spreader (IHS). The images posted on Twitter show that AMD Ryzen Raphael processors will be square-shaped and will measure 45mm by 45mm. AM5 has a single latch and land grid array packaging. The pins will now instead be positioned inside the socket itself, allowing for contact with the LGA pads that are placed under the CPU. The socket no longer features pins underneath the processor, making it a safer option than the previous generation’s. It’s exactly this socket that ExecutableFix has posted renders of, revealing more about the chip.īased on the look of the AM5 socket alone, we can surmise that the retention design for LGA 1718 is very similar to the current Intel Core CPU sockets. The new AMD AM5 will carry the latest LGA 1718 socket, which was created to support the latest generation of Ryzen-based desktops. Previous leaks suggested that Zen 4 Raphael processors will be based on a 5nm core architecture combined with 6nm input/output (I/O) dies. Zen 4 is going to be the direct replacement to AMD’s current mainstream line of processors, the Zen 3, which were code-named Vermeer. Leaks suggest that switching to the AM5 socket will allow AMD to deliver the biggest platform upgrade in several years. Zen 4 Raphael are going to be desktop processors that will bring a vast array of new features.
