Intel Core i5-8500 vs Intel Processor U300

Intel Core i5-8500

► remove from comparison Intel i5-8500

The Intel Core i5-8500 is a mid-range 6-core CPU. The processor belongs to the Coffee Lake generation and was presented in April 2018. It does not support Hyper-Threading, which means it can run six threads simultaneously. The base clock rate is 3 GHz and the CPU can speed up to 4.1 GHz under high load. Despite belonging to the new generation of CPUs, the Core i5-8500 is manufactured in an improved 14nm process.

Performance

The processor offers a strong performance increase compared to the Core i5-7500 due to its two additional cores. Single-core performance has not improved significantly compared to its Kaby Lake predecessor. As a mid-range model, the Core i5-8500 should be suitable for demanding games and programs.

Graphics

The integrated Intel UHD Graphics 630 iGPU is supposed to offer higher performance as its clock rate has been increased by 50-100 MHz. The build is identical to that of the Intel HD Graphics 630. We do expect a performance improvement, but as a low-end solution it will probably only display current games smoothly at reduced details - if at all.

Power Consumption

Intel specifies the TDP with 65 watts. Therefore, well-dimensioned cooling systems should easily manage to deal with the created heat. We expect increased efficiency due to the higher performance.

Intel Processor U300

► remove from comparison Intel U300

The Intel Processor U300 is an entry-level mobile CPU for thin and light laptops of the Raptor Lake-U series. It was announced in early 2023 and offers one performance core (Raptor Cove architecture P-core, similar to Alder Lake) and 4 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading for 6 processing threads when combined with the E-cores. The clock rate ranges from 1.2 to 4.4 GHz on the performance cluster and 0.9 to 3.3 GHz on the efficient cluster. The per-clock performance of the E-cores should be similar to old Skylake cores (compare to the Core i7-6700HQ). All cores have access to 8 MB of L3 cache.

Performance

While we have not tested a single system powered by the U300 as of February 2024, its performance should be very similar to the outgoing Alder Lake Pentium 8505, since there is little difference between the two. The average U300 is set to be 10% to 20% behind the Ryzen 3 5300U and the Core i7-1185G7, as far as multi-thread benchmark scores are concerned, making the former an entry-level chip as of early 2024.

Your mileage may vary depending on how high the CPU power limits are.

Features

The integrated memory controller supports various memory types up to DDR5-4800, DDR4-3200, LPDDR5-5200, and LPDDR4x-4267. The Thread Director (in hardware) can support the operating system to decide which thread to use on the performance or efficient cores for the best performance. For AI tasks, the CPU also integrates GNA 3.0 and DL Boost (via AVX2). Quick Sync in version 8 is the same as in the Rocket Lake CPUs and supports MPEG-2, AVC, VC-1 decode, JPEG, VP8 decode, VP9, HEVC, and AV1 decode in hardware. Several PCIe 4 lanes (x8 for a GPU and two x4 for SSDs) as well as several PCIe 3 lanes are on offer.

The integrated graphics adapter is based on the Xe architecture and offers 48 of the 96 EUs (Execution Units) operating at up to 1.1 GHz.

Power consumption

The U300 has a base power consumption of 15 W, with 55 W being its maximum Intel-recommended Turbo power consumption. The CPU is built with a 10 nm process marketed as Intel 7.
