Intel® Xeon™ Platinum 8260L

The Intel Xeon Platinum 8260L is a server processor with 24 cores and 48 threads, built on the Cascade Lake architecture. It launched in Apr 2019. Clocks run from 2.4 GHz base to 3.9 GHz boost. A 35.75-MB L3 cache backs the cores (2.5 MB per core). It addresses DDR4 memory up to 4.5 GB across 6 channels. The chip drops into the FCLGA3647 socket and exposes PCIe 3.0 (48 lanes). Rated TDP is 165 W. Notable platform capabilities: AVX-512, Extended Page Tables (EPT).

The Intel Xeon Platinum 8260L scores 2,211 in single-core performance and 28,439 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 7,930 for overall performance, 21,581 for productivity performance, 19,621 for creator performance, 36,260 for engineering performance and 13,743 for gaming performance. Its multi-core throughput works out to 1,185 per core, 592 per thread and 172 per watt. Its computed efficiency index is 617. Its performance index is 98, so its overall performance is 2% below the Intel Core i5-12400 (index 100). Each bar shows the score as a share of a reference ceiling, which is the larger of the 99th-percentile score across the Feex CPU database and a fixed baseline.

Scores for individual PassMark CPU Mark test categories. Higher is better. These are measured test scores, not computed from the single-core and multi-core ratings.

In the individual workload tests the Intel Xeon Platinum 8260L scores 134,801 in integer math, 83,488 in floating-point math, 583,695 in compression, 8,788 in cryptography, 1,016 in physics simulation, 43,320 in vector SIMD, 94 in the prime sieve and 71,515 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 129% above in integer math, 82% above in floating-point math, 156% above in compression, 24% below in cryptography, 7% below in physics simulation, 179% above in vector SIMD, 40% above in the prime sieve and 216% above in sorting. Each bar shows the score as a share of that workload's reference ceiling, the larger of the 99th-percentile score across CPUs with a recorded value and a fixed baseline.

The Intel Xeon Platinum 8260L has 24 physical cores and runs 48 logical threads. It runs 2 threads per core. It runs at a base clock of 2.40 GHz and boosts up to 3.90 GHz.

The Intel Xeon Platinum 8260L is a server processor, belongs to the Intel Xeon Platinum family, uses the Cascade Lake architecture, carries the codename Cascade Lake and is manufactured on a 14 nm process. It launched in Apr 2019.

The Intel Xeon Platinum 8260L has 256 KB of L1 cache, 24 MB of L2 cache and 35.8 MB of L3 cache. That adds up to about 60.0 MB of cache, or 2.50 MB per core.

The Intel Xeon Platinum 8260L has a 3-level cache hierarchy: L1 at 256 KB, L2 at 24 MB and L3 at 35.8 MB. L3 is the largest level and makes up about 60% of the cache listed here.

The Intel Xeon Platinum 8260L supports DDR4 memory, addresses up to 5 GB of memory, uses 6 memory channels, runs memory at up to 2,933 MT/s and delivers up to 140.8 GB/s of memory bandwidth. It does not support DDR5 and LPDDR memory.

The Intel Xeon Platinum 8260L does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon Platinum 8260L uses the FCLGA3647 socket, supports PCI Express 3.0 and provides up to 48 PCIe lanes.

The Intel Xeon Platinum 8260L has a rated TDP of 165 W.
