AMD A6-9220e vs Intel Celeron N3450

AMD A6-9220e

The AMD A6-9220e is an entry-level chip from the Stoney-Ridge APU series for notebooks (7th APU generation), which was announced mid 2017. The 9220e is an entry-level Stoney Ridge processor (dual-core version of Bristol Ridge) and integrates two CPU cores (one Excavator module with 2 integer and on FP unit) clocked between 1.6 - 2.4 GHz. It also includes a Radeon R4 GPU, probably with 192 shaders at 600 MHz, as well as a single-channel DDR4-2133 memory controller, H.265 video engine and chipset with all I/O ports. Compared to the similar named A6-9220 the 9220e is significantly slower clocked (2.5 - 2.9 GHz) including the GPU (600 versus 655 MHz) and can be passively cooled thanks to the TDP of 6W.

Architecture

Stoney Ridge is the successor of the Carrizo architecture and the design is almost identical. Thanks to optimized manufacturing processes and more aggressive Boost behavior, however, the clocks are a bit higher at the same power consumption. The memory controller now also supports DDR4-RAM, in this case up to 2133 MHz. Stoney Ridge is the designation for the smaller dual-core and single-core chip, while Bristol Ridge is the bigger quad-core chip with dual-channel memory controller.

Performance

Because of the significantly lower clock speed, the A6-9220e is noticeably slower than the A6-9220. In the Cinebench R15 Multi benchmark the 9220 reaches 38% higher scores, in the single thread test its more than twice as fast (219% versus the 9220 in the HP 255 G6). Compared to Intel CPUs, the A6-9220e is on par with the old Celeron N2820 in Cinebench (single and multi core). Therefore, the CPU is placed in the lowest segment (performance wise) and only suited for light tasks and light multitasking.

Graphics Card

The integrated Radeon R4 (Stoney Ridge) GPU is probably similar to the R5 with 192 active shader units (3 compute cores), but a reduced clock of just 655 instead of 800 MHz. More details about the GPU are available in the linked articles above. 

Power Consumption

AMD specifies the TDP of the A6-9220e with 6 Watts and therefore significantly below the 15 W of the A6-9220. This means the APU can be passively cooled and is a good choice for thin and light notebooks.

Intel Celeron N3450

The Intel Celeron N3450 is a quad-core SoC primarily for inexpensive notebooks and was announced mid 2016. It runs at 1.1 - 2.2 GHz (Single Core Burst, Multi-Core Burst max 2.1 GHz) and is based on the Apollo Lake platform. Similar to the Braswell predecessor, the chip is manufactured in a 14 nm process (P1273) with FinFETs. Besides four CPU cores, the chip also includes a DirectX 12 capable GPU as well as a DDR3L/LPDDR3/LPDDR4 memory controller (dual-channel, up to 1866/2400 MHz).

Architecture

For the first time in a couple of years, Intel completely reworked the CPU architecture of the Atom series. The manufacturer advertises performance gains of roughly 30 percent, but does not reveal any specifics about the individual changes. The new Goldmont architecture should therefore be roughly on par with AMD's Beema/Carrizo-L APUs in terms of per-MHz performance, but it still far behind the more expensive Core CPUs (like Skylake / Kaby Lake).

Performance

The CPU performance of the Celeron N3450 with 4 CPU cores and a clock between 1.1-2.2 GHz should depend a lot on the cooling solution. If the chip can maintain its Boost clock, the N3450 should be about 15-20 percent faster than the old N3710 (Braswell) and compete with an AMD A4-7210. This means the processor is perfectly suited for daily tasks (office, browsing) as well as moderate multi-tasking.

GPU Performance

The HD Graphics 500 (Apollo Lake) is based on Intel's Gen9 architecture, which supports DirectX 12 and is also used for the Kaby Lake / Skylake graphics adapters (like HD Graphics 520). Equipped with 12 EUs and a clock of up to 700 MHz, the performance should be roughly on par with the older HD Graphics (Braswell). This means only older and simpler titles like Counter-Strike: GO or Diablo 3 will run smoothly.

The chip also includes an advanced video engine with hardware support for the playback of VP9 and H.265 material (8-bit color-depth).

Power Consumption

Similar to the predecessor, Intel specifies the TDP with 6 Watts (SDP 4 Watts – Scenario Design Power). The chip can therefore be cooled passively in theory, but SKUs with fans are possible as well.
