Intel Celeron 7300 vs AMD Athlon II N350 vs AMD Athlon II N330

Intel Celeron 7300

The Intel Celeron 7300 is an entry-level mobile CPU for thin and light laptops based on the Alder Lake architecture. It was announced in early 2022 and offers one performance core (P-cores, Golden Cove architecture) and 4 efficient cores (E-cores, Gracemont architecture). The CPU does not support HyperThreading leading to only 5 supported threads at once. The clock rate of the performance cluster is 1000 MHz, the one of the efficient cluster is 700 MHz. The performance of the E-cores should be similar to old Skylake cores (compare to the Core i7-6700HQ). All cores can use up to 8 MB L3-cache. Compared to the faster Core i3-1215U, the Celeron offers one less P-core and lower clock speeds (no Turbo).

Performance

Thanks to the 5 cores, the multi-threaded performance should be clearly faster than the older dual-core Tiger Lake CPUs with 15 Watt (like the Intel Core i3-1115G4). However, due to the missing Turbo and the low clock speed, the single core performance will be very low.

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. The CPU only supports PCIe 4.0 (14 lanes combined with Gen 3).

The integrated graphics card is based on the Xe-architecture and offers 48 of the 96 EUs (Execution Units) operating at up to 0.8 GHz.

The CPU is rated at 15 W base power (TDP, PL1) and 55 W max. power (PL2). The minimum assured power is 12 Watt. The whole SoC is manufactured in a 10nm process at Intel, which is known as Intel 7.

AMD Athlon II N350

The AMD Athlon II N350 is an entry to mid range dual core processor for laptops. Compared to the faster Phenom II and Turion II processors of 2010, the Athlon II N350 features only a 64 Bit FPU (Floating Point Unit), and not 128 Bit as the Athlon II Desktop. Therefore, some rumors also indicate that the N350 could still be based on K8 parts.

The Athlon II N350 offers an integrated DDR3-1066 (or 800 according to Wikipedia) dual-channel memory controller and a 1.6 GHz HyperTransport 3.0 link (HT3200) to the chipset.

The performance of the Athlon N350 should be on par with a 2.2 GHz clocked Pentium T4400 processor of 2009. 

AMD Athlon II N330

The AMD Athlon II N330 is an entry to mid range dual core processor for laptops. Compared to the faster Phenom II and Turion II processors of 2010, the Athlon II N330 features only a 64 Bit FPU (Floating Point Unit), and not 128 Bit as the Athlon II Desktop.

The Athlon II N330 offers an integrated DDR3-1066 (or 800 according to Wikipedia) dual-channel memory controller and a 1.6 GHz HyperTransport 3.0 link (HT3200) to the chipset.

The performance of the Athlon N330 should be on par with a 2.1-2.3 GHz clocked Pentium / Core 2 Duo processor of 2009. First Passmark CPU scores are similar to a Intel Core 2 Duo T4300 with 2.1 GHz.
