Intel Core i7-4578U vs Intel Processor U300

Intel Core i7-4578U

► remove from comparison Intel 4578U

The Intel Core i7-4578U is a LV (low voltage) dual-core processor for large ultrabooks launched in Q3/2014. It is based on the Haswell architecture and is manufactured in 22nm. Due to Hyper-Threading, the two cores can handle up to four threads in parallel, leading to better utilization of the CPU. Each core offers a base speed of 3.0 GHz, but can dynamically increase clock rates with Turbo Boost up to 3.5 GHz.

Architecture

Haswell is the successor to the Ivy Bridge architecture with improvements on both GPU and CPU performance. The CPUs are produced in 22nm and offer an optimized branch prediction as well as additional execution ports, improving the performance per clock by almost 10 percent. Furthermore, new features like AVX2 and FMA should increase the performance in future applications.

Performance

The performance of the Core i7-4578U is slightly above the older and somewhat higher clocked Core i7-3540M. However, when using new instruction sets such as AVX2 the performance can be significantly better. Thus, the CPU has sufficient power for office and multimedia purposes as well as more demanding applications.

Graphics

The integrated Iris Graphics 5100 offers 40 Execution Units (EUs) clocked at 200 - 1200 MHz with Turbo Boost, making it significantly faster than the HD Graphics 4000. As a result, the Iris Graphics competes with dedicated lower mid-range graphics cards (e.g. GeForce GT 720M).

Power Consumption

The i7-4578U is rated at a TDP of 28 W including the graphics card, memory controller, VRMs and the integrated chipset. Therefore, the CPU is suited for larger, well-cooled ultrabooks.

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.
