Overview
SummaryThe Intel Celeron B815 is a laptop processor with 2 cores and 2 threads, built on the Sandy Bridge architecture. It launched in Jan 2012. A 2-MB L3 cache backs the cores (1.6 MB per core). Rated TDP is 35 W.
Performance
12 metricsThe Intel Celeron B815 scores 709 in single-core performance and 754 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 731 for overall performance, 1,483 for productivity performance, 1,691 for creator performance, 702 for engineering performance and 2,316 for gaming performance. Its multi-core throughput works out to 377 per core, 377 per thread and 22 per watt. Its computed efficiency index is 124. Its performance index is 9, so its overall performance is 91% 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.
How these scores are computed
Single-core and multi-core performance are PassMark CPU Mark single-thread and multi-thread ratings. Every other figure on this page's performance section is computed by Feex from those two ratings plus core count, thread count and TDP, so it is a derived value and not a separate benchmark run.
- Overall performance is the geometric mean of the two ratings: the square root of single-core times multi-core.
- Productivity performance is 0.65 times multi-core plus 1.4 times single-core.
- Creator performance is 0.55 times multi-core plus 1.8 times single-core.
- Engineering performance is multi-core times the smaller of 1.4 and (0.9 plus cores divided by 64).
- Gaming performance is 3 times single-core plus 0.25 times multi-core.
- Performance per core, per thread and per watt divide the multi-core rating by physical cores, logical threads and TDP in watts.
- The efficiency index is the square root of single-core times multi-core, divided by the square root of TDP.
- The performance index is overall performance divided by the overall performance of the Intel Core i5-12400 (8,069), times 100.
Workload Benchmarks
8 workloadsScores 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 Celeron B815 scores 3,016 in integer math, 1,617 in floating-point math, 14,468 in compression, 149 in cryptography, 114 in physics simulation, 492 in vector SIMD, 7 in the prime sieve and 1,975 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 95% below in integer math, 96% below in floating-point math, 94% below in compression, 99% below in cryptography, 90% below in physics simulation, 97% below in vector SIMD, 90% below in the prime sieve and 91% below 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.
Core Configuration
6 specsThe Intel Celeron B815 has 2 physical cores and runs 2 logical threads. It does not use a hybrid performance and efficiency core layout. It does not support simultaneous multithreading, so its thread count equals its core count. It runs at a base clock of 1.60 GHz.
