Intel Celeron N4505 vs Intel Core 2 Duo T9550

Intel Celeron N4505

The Intel Celeron N4505 is a dual-core SoC of the Jasper Lake series that is primarily intended for inexpensive and small desktops and was announced in early 2021. The two Tremont CPU cores clock between 2 and 2.9 GHz (single core Burst) and offer no HyperThreading (SMT). The N4505 uses 1.5 MB L2 and 4 MB L3 cache. The chip is built with Intel's first-gen 10 nm process, just like Ice Lake family processors.

CPU Architecture

The processor architecture is called Tremont and a complete redesign compared to the old Golmont Plus cores in the predecessor. According to Intel, the single thread performance of a core could be improved by 30% on average (10 - 80% in all tests of SPECint and SPECfp).

Features

In addition to the dual-core CPU block, the SoC integrates a 16 EU Intel UHD Graphics GPU clocked from 450 - 750 MHz and a LPDDR4(x) dual channel memory controller (up to 16 GB and 2933 MHz). The chip now also partly integrates Wi-Fi 6 (Gig+), 8 PCIe 3.0 lanes, 14 USB 2.0/ 3.2 ports and two SATA 6.0 ports. The package got bigger and measures 35 x 24 mm (compared to 25 x 24 mm for the N5030 e.g.). The SoC is directly soldered to the mainboard (BGA) and can't be easily replaced.

Performance

The average N4505 in our database is just as fast as AMD's dual-core Athlon Silver 3050e and Intel's previous-gen Celeron N4100, as far as multi-thread benchmark scores are concerned. In other words, the Celeron is good for basic day-to-day activities but not much more than that, as of mid 2022.

Power consumption

This Celeron series SoC has a default TDP, also known as the long-term Power Limit, of 10 W, which is low enough to allow for passively cooled designs.

The N4505 is manufactured on the first-gen or the second-gen (no exact data available) 10 nm Intel process making for average, as of late 2022, energy efficiency.

Intel Core 2 Duo T9550

The Intel Core 2 Duo T9550 was the middle class dual core CPU for laptops at the time of introduction. It is similar to the Core 2 Duo P9600 except for the higher TDP of 35 versus 25 Watt.

Due to the relatively high clock speed and 6MB Level 2 cache, the T9550 offers enough performance for demanding games (in 2009) and applications. 

The T9550 uses a Penryn (Montevina Update) core that features 2 integer units, 1 floating point unit, 1 load unit, and 1 store unit in a 14-stages long pipeline. Due to the Wide Dynamic Execution Technology, the core is able to simultaneously execute up to four instructions.

The integrated Enhanced Speedstep is able to downclock the core dynamically to save power (in idle mode).
