What is the GLops of Mali T628MP6? Can't get 17 flops per pipe using OpenGL.

For Mali T604 and T628, peak performance is 17 FP32 FLOPS per ALU per cycle.http://malideveloper.arm.com/downloads/OpenCL_FAQ.pdf shows this is compsed of:

• 7: dot product (4 Muls, 3 adds)
• 1: scalar add
• 4: vec4 add
• 4: vec4 multiply
• 1: scalar multiply

And also in What is exact double precision performance for Mali T628 MP6 (Arndale Octa Board) ? ,  @chrisvarns says 17flops.

And in http://malideveloper.arm.com/downloads/IWOCL.pdf, timhar01 also says 17flops.

But according to my measurement, it can't process dot product with vec4 MAD together. The running time of case 1 and case 2 is the same. Why? How can I get 17 flops?

case 1:

"    color_out5 = color_out5*color5+color6;\n"

"    color_out5 = color_out5*color5+color6;\n"

"    color_out5 = color_out5*color5+color6;\n"

"    color_out5 = color_out5*color5+color6;\n"

"    color_out5 = color_out5*color5+color6;\n"

"    color_out5 = color_out5*color5+color6;\n"

"    color_out5 = color_out5*color5+color6;\n"

"    color_out5 = color_out5*color5+color6;\n"

case2:

"    color_out1 = vec4(dot(color_out1, color1));\n"

"    color_out5 = color_out5*color5+color6;\n"

"    color_out1 = vec4(dot(color_out1, color1));\n"

"    color_out5 = color_out5*color5+color6;\n"

"    color_out1 = vec4(dot(color_out1, color1));\n"

"    color_out5 = color_out5*color5+color6;\n"

"    color_out1 = vec4(dot(color_out1, color1));\n"

"    color_out5 = color_out5*color5+color6;\n"
