I'd like to know that Snapdragon 625 is available for GPU.
On this URL, SnapDragon 625(MSM8953) supports SNPE.
Supported devices:
SnapDragon 820, 835, 625, 626, 650, 652, 653, 660 and 630
So I measured to Qualcomm's SNPE demo app(alexnet) on MSM8953 device.
Then I changed device CPU to GPU on demo app, But it seems not to work GPU.
MSM8953
CPU
ave: 0.209[sec]
max: 0.150[sec]
min: 0.163[sec]
GPU
ave: 0.182[sec]
max: 0.170[sec]
min: 0.172[sec]
On MSM8953 device, libOpenCL.so is allocated here:
/system/vendor/lib/libOpenCL.so
And on this document, it looks that SnapDragon 625(MSM8953) is not supported device.
snpe-1.2.2/doc/html/overview.html
Supported devices:
SnapDragon 835, 821, 820, 660, 652
I'd like to know Snapdragon 625 (MSM8953) is not supported or not.
Or what is needed to check this device is available for GPU ?
(OpenCL's version or other infomation?)
FYI, other device's perfomance that I tried on Qualcomm's SNPE demo app(alexnet).
Snapdragon 820(MSM8996)
CPU
ave: 1.777[sec]
max: 1.947[sec]
min: 1.671[sec]
GPU
ave: 0.035[sec]
max: 0.033[sec]
min: 0.034[sec]
Snapdragon 810(MSM8994)
CPU
ave: 0.216[sec]
max: 0.167[sec]
min: 0.187[sec]
GPU
ave: 0.077[sec]
max: 0.048[sec]
min: 0.059[sec]
In addtion, our device's OpenCL version are...
MSM8953 : 2.0
MSM8994 : 1.2
MSM8996 : 2.0
libOpenCL.so of all device is in this path
/system/vendor/lib/libOpenCL.so
Hi Maggie,
I would like to know whether Snapdragon 625 supports SNPE or not too. Do you get the answer after almost 3 month of your 1st post? I check the Release Note of SNPE 1.8.0, there is no mention regarding Snapdragon 625. Please let me know what's your final invesitgation result. Thanks in advance.
Hi. Sorry the initial question fell through the cracks. The 625 is supported (on the GPU). From reading the initial post, It's not clear why you think it isn't. What error message are you getting when you try to run SNPE on the 625 with the GPU selected as the runtime? Do you think it's not working because of the times you are seeing? What model are you using for your tests? THanks.
