Intel Core 5 315 vs Intel Core i9-14900T Comparison

Where Each One Wins

The benchmark data splits these two processors into very different roles. The Intel Core i9-14900T wins 15 of the 17 recorded head-to-head tests, while the Intel Core 5 315 wins only 2. That near-sweep tells the primary story: the i9-14900T is the heavy lifter for multi-threaded and most single-threaded workloads. Its wins span Cinebench R15, R20, and R23 in both multi-core and single-core runs, plus PassMark tests for data compression, encryption, extended instructions, prime number finding, floating point math, integer math, multithreaded performance, physics, and random string sorting.

The Core 5 315's two victories come in PassMark's single-thread test, where it scores 4021 against the i9-14900T's 4016. The delta is a razor-thin 0.1 percent. This is not a meaningful advantage in real-world terms, but it does indicate the Wildcat Lake chip can hold its own in lightly threaded scenarios despite having far fewer resources. The i9-14900T still beats it in Cinebench R15, R20, and R23 single-core tests by roughly 58 percent, so the PassMark result appears to be an outlier rather than a trend.

The use-case split is clear. The i9-14900T is for sustained multi-core workloads: rendering, video encoding, data processing, and any task that can use 32 threads. The Core 5 315 is for power-constrained mobile environments where single-thread responsiveness matters more than raw throughput. Its 15 watt TDP and single-channel memory bus suggest a design for efficiency, not brute force. The i9-14900T, with a 35 watt TDP and dual-channel memory, targets desktop systems where performance per watt is secondary to absolute performance.

Architecture Differences

The two chips come from different Intel generations and are built for different sockets. The Core 5 315 uses the Wildcat Lake codename, is fabricated on a 3 nm process, and fits the Intel BGA 1516 socket. The i9-14900T is Raptor Lake-R, part of the Core 14th Gen series, uses a 10 nm process, and fits the Intel Socket 1700. The process node gap is substantial: 3 nm versus 10 nm, which explains how the Core 5 315 can deliver competitive single-thread performance with only 6 cores and a 15 watt TDP.

Core counts differ dramatically. The Core 5 315 has 6 cores and 6 threads, meaning no hyperthreading. The i9-14900T has 24 cores and 32 threads, indicating a hybrid design with performance and efficiency cores. The i9-14900T also has a larger die at 257 mm², while the Core 5 315's die size is not recorded in the database. Cache hierarchies reflect the core count difference: the Core 5 315 has 192 KB of L1, 2.5 MB of L2, and 6 MB of shared L3. The i9-14900T has 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. The i9-14900T's L3 cache is six times larger, which aids in multi-threaded workloads that repeatedly access shared data.

Memory support diverges as well. The Core 5 315 supports DDR5 and LPDDR5X with a single-channel memory bus and a recorded bandwidth of 59.7 GB/s. The i9-14900T supports DDR4 and DDR5 with a dual-channel bus, though its memory bandwidth is not recorded in the database. ECC memory is supported on the i9-14900T but not on the Core 5 315, a notable difference for workstation or server use. PCIe lanes also differ: the Core 5 315 offers Gen 4 with 6 CPU lanes, while the i9-14900T offers Gen 5 with 16 CPU lanes.

Integrated graphics differ by generation. The Core 5 315 uses Intel Xe3 Graphics with 2 Xe cores, while the i9-14900T uses UHD Graphics 770. Both are integrated, but the Xe3 architecture is newer. The i9-14900T's launch MSRP is $549, while the Core 5 315's launch MSRP is $340. The i9-14900T released on 2024-01-07, while the Core 5 315's release date is 2026-04-15, indicating a newer product line.

Process node: 3 nm versus 10 nm. Die size: not recorded versus 257 mm².

Cache configurations differ: L1 is 192 KB versus 80 KB per core, L2 is 2.5 MB versus 2 MB per core, and L3 is 6 MB shared versus 36 MB shared. Memory support: DDR5, LPDDR5X versus DDR4, DDR5. Memory bus: single-channel versus dual-channel. Memory bandwidth: 59.7 GB/s versus not recorded. ECC: false versus true. PCIe: Gen 4, 6 lanes versus Gen 5, 16 lanes. Integrated graphics: Intel Xe3 Graphics (2 Xe) versus UHD Graphics 770. Market segment: mobile versus desktop. Release date: 2026-04-15 versus 2024-01-07. Launch MSRP: $340 versus $549. Part number: SAEFC versus SRN3U.

The i9-14900T has a higher boost clock by 1.10 GHz, which contributes to its single-thread Cinebench wins. The Core 5 315 has a higher base clock by 0.40 GHz, but with fewer cores and no hyperthreading, that base clock advantage does not translate into multi-thread wins. The i9-14900T's dual-channel memory bus and larger L3 cache are structural advantages for bandwidth-hungry and cache-sensitive workloads.

Head-to-Head Benchmarks

The i9-14900T dominates every Cinebench test. In Cinebench R15 multi-core, it scores 3104 against the Core 5 315's 1308, a delta of -57.9 percent (meaning the Core 5 315 trails by that margin). The single-core R15 test shows 438 versus 184, a -58 percent delta. R20 multi-core: 12937 versus 5452, -57.9 percent. R20 single-core: 1826 versus 769, -57.9 percent. R23 multi-core: 30803 versus 12981, -57.9 percent. R23 single-core: 4348 versus 1832, -57.9 percent. The consistency of the -57.9 percent delta across all six Cinebench tests indicates a uniform performance gap that scales with clock speed and core count, not a workload-specific quirk.

PassMark results show a wider spread. Data compression: 436066 versus 146143, a -66.5 percent delta. Data encryption: 27062 versus 11119, -58.9 percent. Extended instructions: 23660 versus 13143, -44.5 percent. Find prime numbers: 164 versus 112, -31.7 percent. Floating point math: 92699 versus 42441, -54.2 percent. Integer math: 138149 versus 31690, -77.1 percent, the largest gap in the entire dataset. Multithread: 36239 versus 15272, -57.9 percent. Physics: 2245 versus 1163, -48.2 percent. Random string sorting: 49484 versus 17551, -64.5 percent.

The integer math gap is particularly striking. The i9-14900T's score of 138149 is over 4x the Core 5 315's 31690. This suggests the i9-14900T's hybrid core arrangement and larger cache handle integer-heavy workloads with far greater efficiency. The find prime numbers test shows the smallest PassMark gap at -31.7 percent, indicating that even the Core 5 315's modest core count can keep pace in this specific algorithmic pattern.

The two tests the Core 5 315 wins are PassMark single-thread and singlethread, both scoring 4021 versus 4016, a 0.1 percent delta. This is the only area where the newer 3 nm process and higher base clock show an advantage. The i9-14900T's boost clock of 5.50 GHz does not help in PassMark's single-thread measurement, possibly due to power or thermal constraints that do not affect the lower-TDP Core 5 315.

The Verdict

The data points to a straightforward conclusion. The Intel Core i9-14900T is the superior processor for any workload that can use multiple cores or benefits from a large cache. Its 90th percentile ranking, 51015 average benchmark score, and 15-2 win record against the Core 5 315 make it the clear choice for desktop systems running rendering, data processing, or heavy multitasking. The 24 cores and 32 threads provide a 4x core advantage, and the 36 MB of shared L3 cache supports sustained multi-thread performance.

The Intel Core 5 315 is a different kind of product. Its 72nd percentile ranking and 18188 average benchmark score reflect a mobile-focused design with a 15 watt TDP, single-channel memory, and 6 cores. Its two PassMark single-thread wins, while narrow, show that the 3 nm process and newer architecture can match the i9-14900T in lightly threaded scenarios. The i9-14900T's single-thread Cinebench wins by 58 percent, however, indicate that the PassMark result is not a general single-thread advantage.

For a user prioritizing multi-core throughput, the i9-14900T is the only choice from this comparison. For a user prioritizing power efficiency and mobile operation, the Core 5 315's lower TDP and newer process node are the relevant factors. The i9-14900T supports ECC memory and Gen 5 PCIe, which the Core 5 315 does not. The Core 5 315 supports LPDDR5X, which the i9-14900T does not. The i9-14900T's launch MSRP is $549, while the Core 5 315's is $340.

The benchmark data does not show any scenario where the Core 5 315 beats the i9-14900T by a meaningful margin. Its single-thread PassMark win is 5 points, a rounding error. The i9-14900T's wins range from 31.7 percent to 77.1 percent deltas. The verdict from the database is unambiguous: the i9-14900T is the higher-performing processor, and the Core 5 315 is the more efficient one, with the performance gap reflecting the difference in core count, cache size, and power budget.
