Intel® Xeon™ 6990E+

The Intel Xeon 6990E+ is a server processor with 288 cores and 288 threads, built on the Clearwater Forest architecture. It launched in Apr 2026. Clocks run from 2.2 GHz base to 3.2 GHz boost. A 576-MB L3 cache backs the cores (2.0 MB per core). It addresses DDR5 memory up to 1536 GB across 12 channels. The chip drops into the FCLGA7529 socket and exposes PCIe 5.0 (96 lanes). Rated TDP is 450 W. Notable platform capabilities: AMX (Advanced Matrix Extensions), AMX, AVX-512, Extended Page Tables (EPT).

The Intel Xeon 6990E+ has 288 physical cores and runs 288 logical threads. It does not support simultaneous multithreading, so its thread count equals its core count. It runs at a base clock of 2.20 GHz and boosts up to 3.20 GHz.

The Intel Xeon 6990E+ is a server processor, belongs to the Intel Xeon 6 family, uses the Clearwater Forest architecture and carries the codename Clearwater Forest. It launched in Apr 2026.

The Intel Xeon 6990E+ has 576 MB of L3 cache. That adds up to about 576.0 MB of cache, or 2.00 MB per core. Feex has no recorded L1 cache size for this processor.

The Intel Xeon 6990E+ supports DDR5 memory, addresses up to 1,536 GB of memory and uses 12 memory channels. It does not support DDR4 and LPDDR memory.

The Intel Xeon 6990E+ does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon 6990E+ uses the FCLGA7529 socket, supports PCI Express 5.0 and provides up to 96 PCIe lanes.

The Intel Xeon 6990E+ has a rated TDP of 450 W.
