AMD Fusion E-350
E-350 performance and power consumption
E-350 chip has 2 cores and 40 shaders with 1600/500/100 MHz (CPU/GPU/FSB)
frequencies. Without load frequencies are lowered up to 800/280 MHz and power
consumption is ~8W or 7/9W with (min/max) screen brightnes.
In the high performance mode framerate is ~38 fps (~28 fps with OpenGL
driver) for all GPU based simulations on 512×512 grids
(waves and vortices) and ~12 fps (~9 fps) for the "Two slit interference"
on the 1024×1024 grid. Power consumption increases up to 14-18W.
Double precison floats
Radeon HD 4870 was very good and useful for WebGL but it is out of date
and has limited support for OpenCL. E.g. textures are not supported and
local memory is emulated (= global) but it is powerful and does support
float64 arithmetic as cl_amd_fp64 extension.
E-350 GPU (with 64 bit memory bus width) doesn't support float64
numbers in OpenCL but it supports GL_ARB_gpu_shader_fp64 extension.
See WebGL based Mandelbrot set animation with
double precison floats (for OpenGL drivers only).
Framerate is ~3 fps for 500×500 pixels animation so it is not clear if
Is it useful to emulate float64 in WebCL?
Unfortunately CAL/OpenGL interaction is not supported in my Asus 1215B netbook.
I can use WebCL + WebGL only under Windows 7 + ANGLE (by means of CAL/D3D10
On my netbook with
Gesture driver for TouchPads I can use vertical linear scrolling (one
finger drag along the right touchpad edge) gesture to resize model.
I've found one more useful gesture: click + drag = left mouse button
+ drag (i.e. model rotation).
I can use in Chrome two-finger horizontal scrolling to rotate WebGL models
(see horizontal gesture test).
