Intel® Xeon™ Platinum 8280L

The Intel Xeon Platinum 8280L is a server processor with 28 cores and 56 threads, built on the Cascade Lake architecture. It launched in Apr 2019. Clocks run from 2.7 GHz base to 4.0 GHz boost. A 38.5-MB L3 cache backs the cores (2.4 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 205 W. Notable platform capabilities: AVX-512, Extended Page Tables (EPT).

The Intel Xeon Platinum 8280L scores 2,316 in single-core performance and 41,609 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 9,817 for overall performance, 30,288 for productivity performance, 27,054 for creator performance, 55,652 for engineering performance and 17,350 for gaming performance. Its multi-core throughput works out to 1,486 per core, 743 per thread and 203 per watt. Its computed efficiency index is 686. Its performance index is 122, so its overall performance is 22% above 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 8280L scores 170,775 in integer math, 104,391 in floating-point math, 702,647 in compression, 17,627 in cryptography, 2,862 in physics simulation, 54,097 in vector SIMD, 198 in the prime sieve and 91,434 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 190% above in integer math, 127% above in floating-point math, 208% above in compression, 53% above in cryptography, 163% above in physics simulation, 249% above in vector SIMD, 196% above in the prime sieve and 304% 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 8280L has 28 physical cores and runs 56 logical threads. It runs 2 threads per core. It runs at a base clock of 2.70 GHz and boosts up to 4.00 GHz.

The Intel Xeon Platinum 8280L 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 8280L has 1.75 MB of L1 cache, 28 MB of L2 cache and 38.5 MB of L3 cache. That adds up to about 68.3 MB of cache, or 2.44 MB per core. Each core has 1 MB of private L2 cache.

The Intel Xeon Platinum 8280L has a 3-level cache hierarchy: L1 at 1.8 MB, L2 at 28 MB and L3 at 38.5 MB. L3 is the largest level and makes up about 56% of the cache listed here.

The Intel Xeon Platinum 8280L 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 8280L does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon Platinum 8280L uses the FCLGA3647 socket, supports PCI Express 3.0 and provides up to 48 PCIe lanes.

The Intel Xeon Platinum 8280L has a rated TDP of 205 W.
