Intel Core i3-1315UE vs Intel Core i5-5675C Comparison

Head-to-Head Benchmarks

The benchmark data presents a decisive picture: the Intel Core i3-1315UE wins every single recorded head-to-head comparison, six out of six. The Intel Core i5-5675C does not secure a single win in any of the Cinebench tests. This is a sweeping result, but the margins are surprisingly uniform, which invites a closer look at what the numbers actually imply.

In Cinebench R15 multicore, the i3-1315UE scores 606 against the i5-5675C's 495, a delta of 18.3% in favor of the newer chip. The single-core R15 test shows a nearly identical gap: 85 versus 69, which is an 18.8% advantage for the i3-1315UE. This consistency across single and multicore workloads suggests the i3's advantage is not tied to its extra cores alone, but also to a substantial per-thread performance lead.

Moving to Cinebench R20, the pattern holds. Multicore scores are 2525 for the i3-1315UE and 2063 for the i5-5675C, again an 18.3% delta. Single-core R20 results are 356 versus 291, another 18.3% gap. The i3-1315UE continues its dominance in Cinebench R23, posting 6013 multicore and 849 single-core, compared to the i5-5675C's 4912 and 693. The deltas are 18.3% and 18.4% respectively.

What is striking is the narrow range of these deltas: every test falls between 18.3% and 18.8%. This uniformity indicates that the i3-1315UE's advantage is systemic rather than workload-specific. It is not a case of the i3 winning big in multicore and barely edging out the i5 in single-core; the performance gap is nearly identical regardless of thread count. This suggests the i3-1315UE's architectural efficiency and clock speed superiority are the primary drivers, not just its higher core count.

The average benchmark scores from the database tell a slightly different story. The i5-5675C has an average benchmark score of 1759, while the i3-1315UE sits at 1739. This puts the i5 slightly ahead in the aggregate metric, a reversal of the head-to-head results. However, the database's nearest rival data for the i5-5675C shows it trading places with chips like the Intel Xeon E3-1241 v3 (delta 0.2%) and the Intel Core i7-4790T (delta 0.2%), while losing narrowly to the Intel Xeon E-2224 (delta -0.2%) and AMD Ryzen 5 2400GE (delta -0.4%). The i3-1315UE's nearest rivals include the Intel Core i3-10100 (delta -0.1%), AMD Ryzen 3 4300U (delta -0.2%), Intel Core i5-6600 (delta -0.3%), and Intel Core i7-980X (delta -0.4%). Both chips occupy the 41st percentile among all CPUs, indicating they are positioned similarly in the broader performance landscape, even though the head-to-head Cinebench deltas are so lopsided.

This discrepancy between the head-to-head results and the average benchmark scores is worth investigating. The average score likely incorporates a broader set of benchmarks beyond Cinebench, and the i5-5675C may perform relatively better in those other tests. Yet, in the specific Cinebench suite, the i3-1315UE is unambiguously faster.

The Verdict

The data points to a clear winner for compute-heavy tasks: the Intel Core i3-1315UE. It outperforms the i5-5675C in every Cinebench test recorded, with a consistent 18.3% to 18.8% margin. For any user prioritizing raw rendering performance, multi-threaded workloads, or single-threaded responsiveness, the i3-1315UE is the superior choice based on these measurements.

However, the i5-5675C should not be dismissed entirely. Its average benchmark score of 1759 is higher than the i3-1315UE's 1739, and it is a desktop part with a 65W TDP, which may appeal to users building a stationary system. The i5-5675C also has an unlocked multiplier, allowing for overclocking, a feature the i3-1315UE lacks. For enthusiasts with older Intel Socket 1150 platforms, the i5-5675C could be a drop-in upgrade path, whereas the i3-1315UE is a mobile BGA 1744 part, which is not socketed for user replacement.

The i3-1315UE is a mobile processor with a 15W TDP, which is far more power-efficient on paper, though the database does not record power consumption figures for either chip. The choice ultimately depends on the use case: the i3-1315UE wins on sheer compute performance, while the i5-5675C offers a desktop form factor, an unlocked multiplier, and a slightly higher average benchmark score.

Architecture Differences

The two processors come from vastly different eras and design philosophies. The i5-5675C is built on Intel's Broadwell architecture, using a 14 nm process node. It is a desktop part with 4 cores and 4 threads, meaning it has no hyper-threading. Its base clock is 3.10 GHz and it boosts to 3.60 GHz. The chip has a 65W TDP and fits the Intel Socket 1150. Its cache hierarchy includes 64 KB of L1 per core, 256 KB of L2 per core, and 4 MB of shared L3 cache. The integrated graphics are Iris Pro Graphics 6200, and it supports DDR3 memory on a dual-channel bus with a bandwidth of 25.6 GB/s. It uses PCIe Gen 3 with 16 lanes from the CPU.

The i3-1315UE is a Raptor Lake part, specifically from the Raptor Lake-U family, fabricated on a 10 nm process. It is a mobile chip with 6 cores and 8 threads, indicating a hybrid configuration with performance and efficiency cores. Its base clock is listed as 1200.00 MHz, which is likely the efficiency core base, while the boost clock reaches 4.50 GHz. The TDP is just 15W, and it uses the Intel BGA 1744 socket, which is soldered and not upgradeable. The cache configuration is notably different: 80 KB of L1 per core, 1.25 MB of L2 per core, and 10 MB of shared L3 cache. The integrated graphics are UHD Graphics 64EU. Memory support includes both DDR4 and DDR5 on a dual-channel bus, though the memory bandwidth is not recorded in the database. It uses PCIe Gen 4 with 8 lanes from the CPU.

The architectural leap is significant. The i3-1315UE has a newer process node, a hybrid core design, a much higher boost clock, and a larger L3 cache. The i5-5675C is a traditional 4-core desktop chip with an older memory standard and a lower boost ceiling. The process node difference alone, from 14 nm to 10 nm, likely contributes to the i3's efficiency and clock speed advantages.

Where Each One Wins

The i3-1315UE is the clear winner in all recorded Cinebench tests, both multicore and single-core, across R15, R20, and R23 versions. This makes it the preferred choice for rendering, video encoding, and any application that scales with CPU compute throughput. Its 18.3% to 18.8% margins are consistent, meaning users can expect a similar performance uplift regardless of whether the workload is lightly threaded or heavily parallel.

The i5-5675C wins on the aggregate average benchmark score, 1759 versus 1739, which indicates that outside of the Cinebench suite, it may hold its own or even outperform the i3-1315UE in other types of benchmarks not detailed in the head-to-head data. Additionally, the i5-5675C is a desktop processor with an unlocked multiplier, making it suitable for overclocking and for users with an existing Intel Socket 1150 motherboard. It also has a higher TDP of 65W, which, while less power-efficient, may be preferable in a desktop context where cooling is less constrained.

For a mobile or low-power application, the i3-1315UE is the only logical choice, given its 15W TDP and BGA 1744 form factor. For a desktop build where the user wants the highest possible compute performance in Cinebench, the i3-1315UE is again the winner, despite being a mobile part. The i5-5675C's only advantages are its higher average benchmark score, its unlocked multiplier, and its socketed desktop design.
