Intel Pentium 1403 V2

The Intel Pentium 1403 V2 is a 2-core, 2-thread server/workstation processor built on Intel’s Ivy Bridge-EN architecture. It lists a 2.60 base clock and no boost clock, and it carries 64 KB of L1 cache per core, 256 KB of L2 cache per core, and 6 MB of shared L3 cache. The platform uses DDR3 memory in a triple-channel configuration with 38.4 GB/s of bandwidth, ECC memory support, and 24 PCIe Gen 3 CPU lanes. In the database, the processor sits at the 16th percentile against all CPUs and records an average benchmark score of 668.

Who Should Consider It

Benchmark results position the 1403 V2 at the low end of the performance spectrum. The 2-core/2-thread layout is the central constraint: workloads that want more than two physical threads will not be able to use them. Cinebench R23 shows a multicore score of 1941 and a single-core score of 274. Cinebench R20 shows 815 multicore and 115 single-core. Those are modest scores, and the 16th percentile placement is consistent with that picture. The average benchmark score of 668 is the database’s summary measure behind that placement.

For office-style work that is lightly threaded, the R20 single-core score of 115 and the R23 single-core score of 274 form the practical ceiling. The processor can handle such tasks, but the data does not suggest headroom for heavy multitasking. For creation workloads, the multicore figures are the relevant ones: the R23 multicore score of 1941 and the R20 multicore score of 815 are not competitive with high-throughput server parts, so rendering is not a strength. For gaming, the data set contains no gaming benchmarks, but the absence of integrated graphics and the modest single-core scores orient the part away from consumer gaming. The server/workstation market segment and the ECC memory support define the intended role. This is a processor to match to an existing Socket 1356 platform with ECC DDR3 and 24 PCIe Gen 3 lanes, not a processor selected for raw compute throughput.

Power and Thermals

The processor is rated at 80 W TDP. That is the only thermal figure in the data, and it defines the cooling requirement: an 80 W-class cooler. The 22 nm process, 1,008 million transistor count, and 133 mm² die size describe the physical chip behind that rating. Because no boost clock is listed, the 2.60 base clock is the highest frequency in the data; there is no turbo state to raise thermal output. The absence of integrated graphics also means there is no GPU heat source on the CPU package. An ordinary air cooler in the 80 W class should be sufficient to handle this processor.

How It Compares

Intel Pentium G3460 — The G3460 averages 668, exactly the same as the 1403 V2. The deltaPct of 0 means the two are statistical ties in the database.

Intel Atom x7213RE — The Atom x7213RE averages 669, slightly above the Pentium’s 668. The deltaPct of -0.1 puts the Pentium 0.1% behind. In practical terms, this is parity.

AMD Opteron 3260 HE — The Opteron 3260 HE averages 667, slightly below the Pentium. The deltaPct of 0.1 puts the Pentium 0.1% ahead. The gap is negligible.

Intel Core i5-2520M — The i5-2520M averages 669, and the deltaPct of -0.2 makes this the largest gap in the rival set: the Pentium is 0.2% behind. Even that largest gap is tiny. All four rivals sit within a very narrow score band, with average scores between 667 and 669. The deltaPct values are all close to zero, so the benchmark data does not separate these processors in a meaningful way.

Platform and Compatibility

The 1403 V2 fits Intel Socket 1356 and belongs to the Ivy Bridge-EN family. The part number is SR1B1. Memory support is DDR3 over a triple-channel interface, and the listed memory bandwidth is 38.4 GB/s. ECC memory support is present, matching the server/workstation segment. The CPU provides 24 PCIe Gen 3 lanes, and the data specifically labels those lanes as CPU-only. That means the processor’s direct I/O contribution is 24 lanes, with no integrated graphics block consuming lanes. L1 cache is 64 KB per core, L2 is 256 KB per core, and L3 is 6 MB shared. There is no integrated graphics listed, so display output requires a separate graphics adapter. The multiplier is locked, so the 2.60 base clock is the operating point. Production status is end-of-life, and the release date is 2014-01-08. The platform is not positioned for future CPU upgrades in the data.

Single-Thread vs Multi-Thread Behavior

The benchmark set contains Cinebench R15 multicore at 195, Cinebench R20 multicore at 815, Cinebench R20 single-core at 115, Cinebench R23 multicore at 1941, and Cinebench R23 single-core at 274. The R20 and R23 pairs provide both single- and multi-core results, and both pairs show the same pattern: the multicore score is substantially higher. In R20, the score moves from 115 single-core to 815 multicore. In R23, it moves from 274 single-core to 1941 multicore. The thread count equals the core count at 2 and 2, so these multicore scores come from two physical cores and no extra logical threads. The R15 result of 195 is the only R15 data point, so it cannot be split into single- and multi-thread contributions.

The shared 6 MB L3 cache is available to both cores, which can help when the two threads share data. Still, the absolute multicore values are low, consistent with the 16th percentile placement. Single-thread-bound software will see the lower single-core figures, while software that can use both cores will see the higher multicore figures. The absence of a boost clock means the 2.60 base clock applies to both cores, so the results are produced without a dynamic frequency component. The performance profile favors short, lightly threaded tasks over sustained parallel throughput.
