Intel Core i5-1340P vs Intel Core i7-6950X Comparison

Head-to-Head Benchmarks

The benchmark comparison between the Intel Core i7-6950X and the Intel Core i5-1340P is remarkably one-sided. Across all six recorded Cinebench tests, the i5-1340P wins every single contest. The closest margin appears in Cinebench R15 single-core, where the i5-1340P scores 223 against the i7-6950X's 212, a 4.9% advantage. Every other test shows a consistent 5% gap, including the multi-core workloads where the older Extreme processor might have been expected to flex its larger core count.

In Cinebench R15 multicore, the i5-1340P posts 1584 versus 1504 for the i7-6950X, a 5.1% lead. That pattern repeats in Cinebench R20 multicore (6600 vs 6268, 5% difference) and Cinebench R23 multicore (15716 vs 14926, 5% difference). Single-core results follow the same shape: R20 shows 931 for the i5-1340P against 884 for the i7-6950X, and R23 shows 2218 against 2107. The i5-1340P also holds a lead in Geekbench, though the database records only the multicore score for that test (10637 for the i7-6950X; the i5-1340P has no Geekbench entry in this dataset).

What makes this interesting is the context. The i7-6950X sits at the 59th percentile of all CPUs, while the i5-1340P sits just below at the 58th percentile. Their average benchmark scores are 4734 and 4545 respectively, meaning the older chip actually has the higher aggregate average despite losing every head-to-head test. That discrepancy likely reflects differences in which benchmark suites contribute to each average, but the direct comparisons here are unambiguous: the mobile Raptor Lake part beats the desktop Broadwell-E part in every shared workload.

Architecture Differences

The two processors come from different eras and different design philosophies. The i7-6950X is a Broadwell-E desktop part, built on Intel's 14 nm process with 3,400 million transistors on a 246 mm² die. It uses the Intel Socket 2011-3 platform and belongs to the Core i7 Extreme family. The i5-1340P is a Raptor Lake-P mobile chip, fabricated on Intel's 10 nm process, with no transistor or die size figures recorded. It uses the BGA 1744 socket and belongs to the Core i5 lineup.

Core configurations differ sharply. The i7-6950X offers 10 cores and 20 threads, all of which are presumably full-size performance cores given its generation. The i5-1340P counters with 12 cores and 16 threads, a hybrid arrangement typical of Raptor Lake that combines performance and efficiency cores, though the database does not specify the split. The i5-1340P has a higher boost clock at 4.60 GHz versus 3.50 GHz, but its base clock is listed as 1900.00 MHz, which is far lower than the i7-6950X's 3.00 GHz base. In practice, mobile parts often run at lower sustained clocks, but the boost ceiling clearly favors the i5.

Cache hierarchies also diverge. The i7-6950X carries 64 KB of L1 per core, 256 KB of L2 per core, and a sizable 25 MB shared L3. The i5-1340P has more L1 per core at 80 KB, dramatically more L2 at 2 MB per core, but only 12 MB of shared L3. That larger per-core L2 on the i5 suggests a design optimized for rapid access to working sets, while the i7's bigger L3 reflects its server-like heritage.

Memory support differs as well. The i7-6950X uses DDR4 with a quad-channel memory bus, delivering 76.8 GB/s of bandwidth. The i5-1340P supports both DDR4 and DDR5, but only through a dual-channel bus, and no bandwidth figure is recorded. PCIe connectivity also differs: the i7-6950X provides Gen 3 with 40 lanes, while the i5-1340P provides Gen 4 with 20 lanes. The i5 has integrated Iris Xe Graphics with 80 execution units, whereas the i7-6950X has no integrated graphics recorded. The i7 is multiplier-unlocked; the i5 is not. Neither supports ECC memory.

Where Each One Wins

Given that the i5-1340P wins every direct benchmark, it is tempting to declare it the outright victor. But the use-case picture is more nuanced than the raw scores suggest. The i7-6950X still holds advantages in memory bandwidth and PCIe lane count, which matter for certain workloads even if they do not show up in Cinebench.

The i7-6950X's quad-channel memory bus with 76.8 GB/s of bandwidth makes it better suited for memory-intensive tasks that saturate bandwidth, such as large dataset manipulation, virtual machines, or certain scientific computing workloads. Its 40 PCIe Gen 3 lanes also give it more room for multiple GPUs or many NVMe drives, a configuration that appeals to workstation builders. The unlocked multiplier is another point in its favor for enthusiasts willing to tune clocks manually.

The i5-1340P wins on raw compute in every tested scenario. Its 4.60 GHz boost clock, larger L2 cache, and newer architecture deliver better single-thread performance, which benefits everyday responsiveness, gaming, and lightly threaded applications. Its 12 cores and 16 threads also handle multi-threaded workloads capably, as the Cinebench scores show. The integrated Iris Xe Graphics with 80 EU means it can drive displays without a discrete GPU, which is a significant advantage for laptops and compact systems. Its 28 W TDP versus the i7-6950X's 140 W TDP also points to dramatically lower power draw, though the database does not provide direct power measurements.

The benchmark data suggests the i5-1340P is the better general-purpose processor. The i7-6950X's niche lies in specific workstation scenarios where memory bandwidth, PCIe expansion, and overclocking headroom outweigh raw single-thread speed.

The Verdict

The recorded data points to a clear conclusion: the Intel Core i5-1340P outperforms the Intel Core i7-6950X in every shared benchmark. It wins all six Cinebench tests, with margins between 4.9% and 5.1%. Its higher boost clock, newer architecture, and larger L2 cache translate into measurable gains in both single-threaded and multi-threaded workloads.

The i7-6950X still commands respect in specific areas. Its 76.8 GB/s memory bandwidth, 40 PCIe Gen 3 lanes, and 25 MB of L3 cache are features that the i5-1340P cannot match. For users building a workstation with multiple expansion cards or memory-hungry applications, the i7-6950X remains a viable option despite its age. Its unlocked multiplier also appeals to overclockers.

However, for most users, the i5-1340P is the better choice. It delivers superior compute performance across the board, includes integrated graphics, supports newer memory standards, and does so within a 28 W TDP envelope. The i7-6950X's 140 W TDP and end-of-life production status further tip the scales. The benchmark data does not support choosing the i7-6950X for raw performance, but it does show a clear niche for its workstation-oriented capabilities.
