Did you think Intel’s LGA4677 socket for 4th Gen Xeon Scalable ‘Sapphire Rapids’ processors was huge? A detailed image of Intel’s next-generation LGA7259 socket has emerged (Courtesy of Marvin Sevilla aka @SprayOnCopper) and shows that this future socket will be much larger than the current design. In fact, the LGA7259 could probably challenge AMD’s SP5 socket with his 6,096 contacts.
measurement 61×82mm Without the retention mechanism, Intel’s LGA4677 for Xeon Scalable ‘Sapphire Rapids’ and ‘Emerald Rapids’ CPUs is already a fairly large socket. Still, it’s significantly smaller than the company’s upcoming LGA7259 socket for Intel’s Granite Rapids and Sierra Forest CPUs, and has more cores than Intel’s previous offerings, as images published by Marvin Sevilla show. , consumes more power.
The actual dimensions of Intel’s LGA7259 have not been released (they available to developersof course), but based on what we know about the dimensions of Intel’s current 4th Gen Xeon Scalable CPUs, it looks like we’re dealing with a socket of about 66 by 92.5 mm including the retention mechanism. , AMD’s 6,096-pin SP5 socket for EPYC ‘Genoa’ and ‘Bergamo’ processors 93.4mm x 120.3mm It has a retention mechanism that makes both Intel’s LGA4677 and LGA7259 smaller.
Intel’s 4th Gen Xeon Scalable ‘Sapphire Rapids’ processors have a thermal design power of up to 350W, but according to media reports, the LGA4677 socket has a peak power delivery limit of 764W. Intel’s next-generation CPU in the LGA7259 package is said to feature a TDP of around 500W, so peak consumption could exceed 1 kW.
Meanwhile, in addition to more power, Intel’s LGA7259 socket will enable a 12-channel DDR5 and DDR5 MCR memory subsystem and some additional I/O.
No word yet on how much Intel’s LGA7259 socket will cost. Modern sockets with thousands of contacts on a small pitch (Intel’s LGA4677 has a grid spacing of 0.81389 x 0.9398mm) are difficult to manufacture and therefore expensive. Depending on where you buy $101 and $124 per unit in quantities of 10,000 units. Intel’s LGA7259 is considerably larger and has more contacts, so we can expect this socket to be even more expensive than its predecessor.
The 7259-pin socket itself is unlikely to have a significant impact on next-generation server pricing, as socket cost is only a small part of a server’s bill of materials. Still, bearing in mind that CPU power consumption scales with pin count, server platform manufacturers are choosing not only more expensive sockets, but also more durable components, better cooling systems, and A more advanced voltage regulation module with a higher wattage power supply should be used. Above all.
