Intel Core i5-540UM vs Intel Processor U300
Intel Core i5-540UM
► remove from comparisonThe Intel Core i5-540UM is a Ultra Low Voltage dual-core processor for small and light laptops. It is clocked with 1.2 - 2 GHz (if Turbo Boost is enabled). Each core is based on the Nehalem (Westmere) micro-architecture. Hyperthreading enables the Dual Core CPU to handle 4 threads at once (for a better usage of the pipeline). AES, VT-d and Trusted Execution are activated (compared to the 430UM).
A feature of the new Core i5-540UM is the integrated graphics card (called Intel HD Graphics) and memory controller. Both are on a separate die that is still manufactured in 45nm whereas the CPU die is already manufactured in the new 32nm process.
Due to the integrated memory controller, the HyperThreading and Turbo Boost, the Core i5-540UM is faster than a similar clocked Core 2 Duo (1.2 GHz) in all (us known) applications and benchmarks. Still the Turbo Boost may not trigger very often (sometimes it is even not activated in the BIOS) and therefore the maximum of 2 GHz may not be important.
The integrated Intel Graphics Media Accelerator HD (GMA HD) graphics card is between 166-500 MHz (Turbo Boost) and therefore the base speed is clearly below the non low voltage versions. The performance should still be faster than the old GMA 4500MHD.
The power consumption of 18 Watt TDP (max.) counts for the whole package and therefore it is clearly better than the 17 Watt TDP of the Core 2 Duo SL-series (CPU alone).
Intel Processor U300
► remove from comparisonThe 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.
