In the latest benchmark leaks, the results of the Intel Core Ultra 7 265K, a CPU from the Arrow Lake series, were published on Geekbench. These show that the performance in multi-threaded applications has been improved compared to previous models and competitor processors. The processor has a total of 20 cores and 20 threads, which are made up of 8 P-cores (performance cores) and 12 E-cores (efficiency cores). The processor is equipped with 30 MB L3 cache and 36 MB L2 cache, which results in a total memory size of 66 MB.
The base clock rate of the P-cores is 3.9 GHz, while the E-cores operate at a base clock rate of 3.3 GHz. The boost clock rates are up to 5.5 GHz for the P-cores and 4.6 GHz for the E-cores. The processor has a TDP of 125W under standard load (PL1) and a maximum TDP of 250W under load (PL2). In the Geekbench 6 benchmark, the Core Ultra 7 265K achieved 3283 points in the single-core test and 22,293 points in the multi-core test. These results place it at the top of the desktop CPU rankings. Compared to its direct predecessor, the Core i7-14700K, the increase in performance is around 11.4 % in the single-core range and 15.6 % in the multi-core range.
Comparison with other processors
In the single-core tests, the Core Ultra 7 265K is around 2.2 % behind the AMD Ryzen 9 9950X, which is due to differences in the maximum boost clock rates. The Core Ultra 7 265K achieves a maximum boost of 5.5 GHz, while the Ryzen 9 9950X reaches up to 6.0 GHz. The Intel Core i9-14900K, another competitor model, is around 6.3% behind the Core Ultra 7 265K in the single-core tests, although this processor has a slightly higher maximum clock rate of 5.7 GHz. In the multi-core comparison, the Core Ultra 7 265K is around 8.4% ahead of the Ryzen 9 9950X and around 7% ahead of the Core i9-14900K. This is remarkable, as the Core Ultra 7 265K only has 20 threads, while the Ryzen 9 9950X and the Core i9-14900K both offer 32 threads.
Factors influencing performance
The increased performance of the Core Ultra 7 265K can be attributed to several factors. One of them is the possible improvement of the BIOS and microcode firmware, which helps to better reflect the actual performance of the Arrow Lake platform. In addition, the use of test samples that are closer to the final sales products could also play a role, and another factor could be the memory configuration. In the tests, DDR5 memory with 64 GB capacity was used, whereby higher memory speeds could lead to better results. The Arrow Lake platform is expected to support particularly fast memory, which should be taken into account in future tests.
The actual power consumption of the Core Ultra 7 265K during the tests is unclear, as the benchmarks do not provide details about the power configuration used. Therefore, it is possible that the difference in performance is also due to different power profiles (standard vs. performance profile). In conclusion, further tests and independent evaluations are necessary to get a complete picture of the performance of the Core Ultra 7 265K. These are expected in the period around October 24, 2024, the planned release date of the CPU.
