Intel Core 3 305 vs Intel Core i5-14500T Comparison

The Intel Core 3 305 and Intel Core i5-14500T serve fundamentally different purposes, a fact confirmed by the benchmark data. The Core i5-14500T dominates in heavily threaded and memory-intensive workloads, winning 12 of the 17 head-to-head comparisons. The Core 3 305, however, wins in specific single-threaded and specialized tasks, including the important Cinebench R23 multi-core test. The data indicates a clear split: the i5-14500T is the raw throughput leader, while the Core 3 305 delivers superior efficiency in select workloads.

Where Each One Wins

The Intel Core i5-14500T is the clear winner for productivity and content creation. Its 14 cores and 20 threads provide a massive advantage in multi-threaded applications. The PassMark multithread score of 22910 is 32.6% higher than the Core 3 305's 15439. This advantage extends to integer math, where the i5-14500T scores 80922 versus 32295, a 60.1% lead, the largest margin in the comparison. Data compression results show a 44% gap, with the i5-14500T scoring 262417 compared to 146857. The i5-14500T also wins in floating-point math (58869 vs 42284), random string sorting (28462 vs 17623), and data encryption (15410 vs 11019). The older Cinebench R15 and R20 tests also favor the i5-14500T by margins between 26.2% and 34.6%.

The Intel Core 3 305 wins in five specific areas. Its Cinebench R23 multi-core score of 13123 is 11.3% higher than the i5-14500T's 11790, a notable reversal from the older Cinebench versions. The Core 3 305 also wins the PassMark single-thread test with a score of 3977, a 6.5% advantage over the i5-14500T's 3736. The find prime numbers test shows a 42% lead (115 vs 81), a significant margin for that specific algorithm. The Cinebench R23 single-core result is nearly tied, with the Core 3 305 edging ahead by 0.8% (1852 vs 1838). These wins point to the Core 3 305's strength in lightly threaded workloads and its newer architecture's efficiency in certain rendering tasks.

Architecture Differences

The two processors come from different design philosophies. The Core 3 305 uses the Wildcat Lake codename and a 3 nm process node, fabricated by Intel. The Core i5-14500T uses the Raptor Lake-R codename and Raptor Lake architecture on a 10 nm process node, also fabricated by Intel. The Core i5-14500T has a die size of 215 mm², while the Core 3 305 has no recorded die size. The process node difference is significant: the Core 3 305's 3 nm node is a newer, denser manufacturing process compared to the i5-14500T's 10 nm node.

Core configuration differs sharply. The Core 3 305 has 6 cores and 6 threads, meaning no hyperthreading. The Core i5-14500T has 14 cores and 20 threads, a hybrid configuration that provides 6 additional threads beyond its core count. Clock speeds also differ, with the Core 3 305 boosting to 4.30 GHz from a 1.50 GHz base, while the i5-14500T boosts to 4.80 GHz from a 1.70 GHz base. The i5-14500T has the higher boost clock, but the Core 3 305 wins the single-thread PassMark test anyway.

Cache layouts are entirely different. The Core 3 305 has 192 KB of L1 cache, 2.5 MB of L2 cache, and 6 MB of shared L3 cache. The Core i5-14500T has 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 24 MB of shared L3 cache. The i5-14500T's 24 MB L3 cache is four times the Core 3 305's 6 MB, which helps explain its dominance in data-heavy workloads like compression and integer math.

Memory support also diverges. The Core 3 305 supports DDR5 and LPDDR5X memory with a single-channel memory bus and a recorded memory bandwidth of 59.7 GB/s. The Core i5-14500T supports DDR4 and DDR5 with a dual-channel memory bus and no recorded memory bandwidth figure. The i5-14500T supports ECC memory, while the Core 3 305 does not. The i5-14500T offers more PCIe lanes at a newer revision: Gen 5 with 16 lanes compared to the Core 3 305's Gen 4 with 6 lanes. Integrated graphics differ as well, with the Core 3 305 using Intel Xe3 Graphics (1 Xe) and the i5-14500T using UHD Graphics 770.

The Verdict

The database records show two processors with different missions. The Intel Core i5-14500T is the choice for multi-threaded desktop workloads. Its 14 cores, 20 threads, 24 MB of L3 cache, and dual-channel memory support deliver decisive wins in integer math, compression, encryption, and multithread tests. The 35 W TDP and Socket 1700 platform position it as a desktop part, and its 80th percentile ranking reflects strong overall performance.

The Intel Core 3 305 is the choice for mobile efficiency and specific single-threaded tasks. Its 15 W TDP, 3 nm process node, and single-channel memory define a low-power mobile design. The 72nd percentile ranking is lower overall, but the Core 3 305 wins the Cinebench R23 multi-core test and the PassMark single-thread test, showing that newer architecture can overcome core count disadvantages in certain scenarios. The find prime numbers result, a 42% win, suggests the Core 3 305 handles specific algorithm patterns more efficiently.

The i5-14500T's 80th percentile versus the Core 3 305's 72nd percentile quantifies the overall performance gap. The i5-14500T's average benchmark score of 28065 is 53.3% higher than the Core 3 305's 18302. The nearest rivals confirm the positioning: the Core 3 305 sits near the Intel Core i3-14100 and AMD Ryzen 5 2600E, while the i5-14500T sits near the AMD Ryzen 5 PRO 8500GE and Intel Core i9-12900H. For users requiring maximum multi-threaded throughput, the i5-14500T is the clear choice. For users prioritizing single-thread performance and lower power consumption in a mobile form factor, the Core 3 305 delivers the better results.
