Intel Core i7-14700K vs Intel Core Ultra 7 265U vs Intel Core i5-14500T

Intel Core i7-14700K

The Intel Core i7-14700K is a desktop processor based on the Raptor Lake architecture, which inherits the 13th generation of Intel Core processors with minor improvements. The processor offers a base clock of 2.5 GHz or 3.4 GHz and reaches up to 5.6 GHz in Turbo. The basic CPU structure remains unchanged. The Intel Core i7-14700K features 8 P-cores and 12 E-cores, allowing up to 28 threads to be processed in parallel. The Intel Core i7-14700K still offers a freely selectable multiplier, which makes overclocking much easier. It is also based on the LGA 1700 socket, which was already introduced with Alder Lake.

Performance

Compared to the Intel Core i7-13700K, the IPC of the new Core i7-14700K has only been increased slightly. This means that the difference in performance is only due to the higher number of efficiency cores (12 vs. 8) and higher clock rates.

Graphics unit

Like the Intel Core i7-13700K, the Intel Core i7-14700K also has an integrated graphics unit. The Intel Iris Xe architecture continues to serve as the basis. In terms of performance, however, nothing has changed with the Intel UHD Graphics 770.

Power consumption

The TDP of the Intel Core i7-14700K is 125 Watts, with the option of consuming up to 253 watts in Turbo mode.

Intel Core Ultra 7 265U

The Intel Core Ultra 7 265U is an upper mid-range CPU with 12 cores from the Arrow Lake U series, which was introduced at the beginning of 2025. The SoC is based on a tile/chiplet design. The chip is similar to the Meteor Lake U series, but the compute part is manufactured using the modern Intel 3 process and therefore offers higher clock rates.

The smaller compute tile (compared to the H processors) offers 2 performance cores (P cores, Redwood Cove architecture, SMT) and 8 efficiency cores (E cores, Crestmont architecture). The P-cores support hyperthreading (therefore 14 threads together) and clock up to 5.3 GHz. The E-cores clock at a maximum of 4.2 GHz. In addition, there are now two more low-power efficiency cores on the low-power island, so the compute tile can be completely deactivated when idle and during simple tasks in order to save power.

Performance

Thanks to the significantly higher clock rates, the Core Ultra 7 265U should be significantly faster than the old Core Ultra 7 165U (12 cores, max 4.9 / 3.8 GHz, 12 MB cache). Due to the 12 cores, the multi-thread performance is very good, but can be limited by the low TDP (especially under long load).

Graphics unit

The Core Ultra 7 265U offers a new Arc-based iGPU called Intel Graphics with 4 Xe cores and 64 EUs that reach a maximum of 2.1 GHz. However, the performance is clearly below the new Arc iGPU in the H series.

Features

Arrow Lake-U has integrated WiFi 6E (WiFi 7 optional) and Thunderbolt 4 (4x). The integrated memory controller now supports LPDDR5/x-8400 or DDR5-6400 (max. 128 GB). A dedicated NPU (2x Gen3 Neural Compute Engines) is now used. The Xe Media Engine supports MPEG-2, AVC, VC-1 Decode, JPEG, VP8 Decode, VP9, HEVC and AV1 Decode up to 8K 10-bit HDR. The chip now supports PCIe-5.0 (x8 for GPU) and PCIe-4.0 (three x12 for SSDs).

Power consumption

The Intel Core Ultra 7 265U is specified with 15 watts TDP (base) and 57 watts (PL2) max. turbo power. Meteor Lake consists of five individual chips, whereby the processor part is manufactured in the new Intel 3 process (5nm). The graphics unit is produced at TSMC in N5 and the SoC and I/O tile in the older N6 process. These 4 chips are then applied to the 22nm base tile using the Foveros process.

Intel Core i5-14500T

The Intel Core i5-14500T is a power-efficient desktop processor based on the Raptor Lake architecture, which was introduced in October 2022. The processor offers a base clock of 1.7 GHz and reaches up to 4.6 GHz in Turbo. The hybrid CPU architecture, which was introduced with Alder Lake, also benefits the Raptor Lake processors. The suffix T stands for a particularly economical CPU model and with a TDP of just 35 watts (PL1 = 35 watts), these processors are ideally suited to small, compact systems.

Performance

The low power consumption ultimately results in slightly lower performance compared to the Intel Core i5-14500. Depending on how the PL2 (92 watts) is defined, there may be noticeable differences in multi-core performance. Compared to the Intel Core i5-12500T, the Intel Core i5-14500T is superior due to the higher number of physical computing units. Compared to the Intel Core i5-13500T, there is no noticeable increase in performance due to the same number of computing units.

Graphics unit

Like the Intel Core i5-13500T, the Intel Core i5-14500T offers an integrated graphics unit. The Intel Iris Xe architecture continues to serve as the basis. In terms of performance, however, not much has changed with the new Intel UHD Graphics 770. The iGPU of the Intel Core i5-14500T also clocks 100 MHz higher, but this does not make a noticeable difference in everyday use.

Power consumption

The TDP of the Intel Core i5-14500T is 35 watts, with the option to increase this to up to 92 watts in Turbo mode. Compared to the Intel Core i5-13500T, nothing has changed in terms of power consumption.
