The Intel Pentium T4500 (or Intel Pentium Dual-Core T4500) is an entry level dual-core CPU for laptops. Compared to the Core 2 Duo CPUs, the T4500 has only 1 MB Level 2 cache and some power saving technology is deactivated.
Therefore, the power consumption in idle mode should be a bit above similar clocked Core 2 Duo CPUs. Furtheremore, virtualization technology VT-x is also not available for the T4500.
Due to the slow clock rate and the small level 2 cache, the Pentium T4500 will limit the performance of demanding 3D games (e.g. Supreme Commander). For entry level applications like office, SD video cutting, image processing, Internet and casual gaming, the T4500 should be sufficient.
The Pentium T4500 is based on the Intel Penryn core and features 2 integer units, 1 floating point unit, 1 load unit, and 1 store unit in a 14-step pipeline.
The Intel Pentium Silver J5040 is a quad-core SoC primarily for inexpensive mini-PCs and was announced late 2019. It runs at 2 GHz (base) to 3.2 GHz (single core burst) and is based on the Gemini Lake platform (refresh). Similar to the Apollo Lake predecessor, the chip is manufactured in a 14 nm process with FinFETs but offers slightly improved processor cores, double the amount of L2 cache, a smaller package, a better GPU architecture and a partly integrated WiFi support. Besides four CPU cores, the chip also includes a DirectX 12 capable GPU as well as a DDR4/LPDDR4 memory controller (dual-channel, up to 2400 MHz). The SoC is not replaceable as it is directly soldered to the mainboard.
Architecture
The processor architecture is still called Goldmont Plus. Compared to the older Goldmont cores in Apollo Lake, they feature an increased level 2 cache (to 4 MB). That means the per-clock-performance should be a bit better, but not near the Core CPUs like Kaby Lake Y.
Performance
Thanks to the higher clock speed and TDP, the Pentium J5040 is slightly faster than the mobile counterpart, the Pentium Silver N5030. Compare to AMD, it ranks on average slightly higher compared to the Athlon Silver 3050e (Zen based Dual-Core) that wins in single-core tests but looses out in multi-threaded tests. Intel Core i3 from 2019 (like the i3-1005G1) are clearly faster and win even in multi-threaded tests easily although being only dual-core CPUs.
