Hello,
I've made a chart that can help you compare different CPU architectures and speeds vs. performance:

Is it scorpion or snapdragon? How is it compare to hummingbird processor?
Sent from my SE_X10i using Tapatalk
Snapdragon is the SOC, and Scorpion is the name of the CPU core. It's arm based like the hummingbird, and as far as I know, the performance is very similar (some +&- between the two)
Both are same, except the GPU part, Snapdragon MSM8255 which uses Adreno 205 GPU ( Adreno is a rebranded AMD Z430 originally developed by ATi as Imageon then AMD sold it to Qualcomm )... Hummingbird in the other hand uses the PowerVR SGX 540 GPU from Imagination Technologies...
from performance POV, PowerVR SGX 540 is a little bit faster than Adreno 205 ( over all performance, in some benchmarks the SGX 540 is notable faster like in GLBenchmark 2.0 ), but the CPU part of the hummingbird limit it's power, the same GPU when used in a dual core SOC like OMAP 4430 ( used in LG Optimus 3D ) performs better... just to note, Samsung used another SOC in Galaxy S2 that SOC uses a different GPU named Mali-400MP which is slower than SGX 540... but being a dual-core helps the Mali-400MP to be faster than SGX 540...
Hi I'm trying to decide between int version and US version and I'd like to know which GPU is the most powerful, I already know about dual core vs quadcore (dual core being slightly better than the quadcore version) Thanks
Some info in the links in OP.

SGX531 is a old gpu (create in Oct 2006) but recently a new version of SGX531 come : SGX531 Ultra. Same numbers of units but a big overclock. His frequency is estimated between 400 and 522 Mhz. Compared at the SGX540(Nexus S, Galaxy S base frequency, 200 mhz for memory) it's a huge difference. I know overclocked version of SGX 540 exist.(Galaxy Nexus, Optimus 3D, etc). But the architecture of SGX 531 is exactly the half of architecture of SGX 540. So in theory, if we set the frequency at the exact double of SGX 540, we should get the same results but... the reality is quite different. In fact after many tests, I've comparables results of SGX531 and SGX540. Unfortunately I do not know the exact frequency used by the SGX531. Many news phones(a lot of chineses phones apparently) use this "new" gpu on low cost smartphones. The tests were performed on models with similar configurations. (mono core processor 1 Ghz, 512 mb ram, same resolution 800*480)
Results :
GL Benchmark 2.7 : (Theorical Benchmark)
Triangle throughput Textured C24Z16 Offscreen : SGX531 Ultra 7,866,918 Triangles/sec | SGX540 4,490,935 Triangles/sec 17% Better
Triangle throughput Textured C24Z16 Onscreen : SGX531 Ultra 14,021,563 Triangles/sec | SGX540 11,053,386 Triangles/sec 27% Better
Fillrate C24Z16 Offscreen : SGX531 Ultra 267,150,928 Texels/sec | SGX540 219,676,416 Texels/sec 22% Better
Fillrate C24Z16 Onscreen : SGX531 Ultra 197,397,584 Texels/sec | SGX540 128,086,480 Texels/sec 54% Better
Taiji 3D Benchmark : (Geometry Benchmark)
SGX531 Ultra : 9,21 fps / SGX540 : 11,15 fps 21 % Lesser
Nenamark 2 :
SGX531 Ultra : 23,5 fps / SGX540 26,3 fps 12 % Lesser
We notice the overwhelming superiority of SGX531 Ultra on theoric tests but SGX540 is better in real conditions
With this results i can estimated the frequency of SGX531 Ultra, 522 Mhz is possible. (the fillrate is very dependent of processor, the processor used for the tests of SGX540 is slightly recessed relative to that of SGX531 but is not limited mostly)
Hello everybody
I'm still using my Samsung Galaxy S5 but it's gotten too slow.
So I want a new phone. Not sure whether Xiaomi Redmi Note 4 or Redmi Note 5 Pro.
I did a comparison:
Chipset
S5: Qualcomm MSM8974AC Snapdragon 80, Quad-core 2.5 GHz Krait 400,Adreno 330
Redmi Note 4: Qualcomm MSM8953 Snapdragon 625, Octa-core 2.0 GHz Cortex-A53, Adreno 506
Redmi Note 5 Pro : Qualcomm SDM636 Snapdragon 636, Octa-core 1.8 GHz Kryo 260, Adreno 509
Why would anyone buy the Redmi Note 5 Pro with a slower CPU clock speed? Does the Kryo 260 have some other features which make it faster in the end? I couldn't find many details googeling for both of the CPUs.
Your advice is appreciated.
Have a nice day
SD636 scores higher in benchmarks and has better GPU
Snap 636 is quite far better than Snap 801/805 and Snap 625. We can also overclock it and still keep good battery life
