Intel tend to release lots of processors, and it’s not also clear how they perform against each others, but generally the rank from slowest to highest goes something like Atom < Celeron < Pentium < Core M < Core i3 < Core i5 < Core i7. Recently, I’ve seen and reviewed a few low power Intel Atom x7-Z8700 “Cherry Trail” and Intel Celeron N3150 “Braswell” mini PCs, both quad core processors @ 1.6 GHz (base), and I could not find much differences between the two during use.
So to have a clear and objective view of the relative performance of the two processors, I’ve compared the results I got with Intel Atom x7-Z8700 based Beelink BT7 mini PC to the ones I got with MINIX NGC-1 mini PC powered by Celeron N3150 processor in the table below. Both machines have been designed quite well (good heat dissipation) and with storage devices having similar performance. A ratio greater than one (green) means the Celeron processor is faster, and if it is lower than one (red) the Atom processor prevails.
Intel Atom x7-Z8700 @ 1.6 GHz / 2.48 Ghz (Turbo)
Intel Celeron N3150 @ 1.6 GHz / 2.08 GHz (Turbo)
|PCMark 8 Accelerated|
|Web Browsing – JunglePin||0.59309s||0.63426s||0.94|
|Web Browsing – Amazonia||0.19451s||0.2141s||0.91|
|Casual Gaming||7.96 fps||9.7 fps||1.22|
|Video Chat playback||29.99 fps||30.01 fps||1.00|
|Video Chat encoding||301 ms||193.333 ms||1.56|
|Ice Storm 1.2||23,999||23,032||0.96|
|Cloud Gate 1.1||2,185||1,961||0.90|
|Sky Diver 1.0||1,131||1,108||0.98|
So in the end, both processors have a very close performance, except for video chat encoding where the Atom processor is about 56% slower than the Celeron processor. The Atom’s 16 EU GPU @ 200/600 MHz is faster than the Celeron’s 12 EU GPU @ 300/640 MHz in most case, but only marginally. Both SoCs are capable of decoding 4K videos with H.264 and H.265 video codecs. Systems based on the Intel Axom x7-Z8700 processor could consume less electricity as Atom x7 has a 2W SDP, while Celeron N3150 a 4W SDP, but the power consumption of a complete mini PC also depends on its overall design.
So there seems to be very little to gain by purchasing a system with Celeron N3150 “Braswell” processor over one with a Atom x7 “Cherry Trail processor, if a mini PC matches your requirements. One noticeable advantage of Braswell processors should be Linux support with the default/standard ISO images, while Atom x7 systems currently require community hacked ISO images for support of features such as HDMI audio, WiFi and Bluetooth. You can also find a side-by-side comparison of the features of the two processor on Intel website.
