Xeon 656 20-core server processor
The Intel Xeon 656 is a 20-core server processor built on the Intel 3 process with Granite Rapids cores. It operates at a 2.9 GHz base frequency and reaches a 4.8 GHz maximum turbo frequency. The chip provides 40 threads and 72MB of L3 cache for multi-threaded server workloads.
LGA 4710 socket and DDR5 6400 MHz memory
This processor requires a motherboard with an LGA 4710 socket and supports eight channels of DDR5 memory at 6400 MHz. The platform is limited to single-socket configurations and delivers 128 lanes of PCI Express 5.0 connectivity. Verify that your chassis and power delivery can accommodate a 210 W thermal design power.
Sustained 210 W load with 252 W turbo peaks
Under continuous heavy load the CPU runs at its 210 W thermal design power, while short bursts can draw up to 252 W. The 20 performance cores maintain high throughput for virtualisation, database and compute tasks without efficiency cores to manage. Adequate cooling is essential to prevent throttling during extended operation.

商品問答
Does the Intel Xeon 656 PK8072007104700 include a heatsink or fan in the box, or must I buy a cooler separately?
The processor is sold as a tray unit without a heatsink or fan; a compatible LGA 4710 cooler rated for 210 W base and 252 W turbo must be purchased separately.
When should I choose the 20-core Xeon 656 over other SKUs in the Xeon 6 line?
Select the 656 when a single-socket server needs 20 performance cores, 40 threads, 72 MB L3 cache and a 2.9 GHz base clock with 4.8 GHz max turbo within a 210 W envelope.
What does the 4.8 GHz max turbo figure deliver in a live server running AVX-512 workloads?
The 4.8 GHz Intel Turbo Boost Max 3.0 frequency can be reached on up to two cores when power and thermal headroom allow, accelerating AVX-512 vector code and AMX matrix operations.
