I agree with you two, though I tend to add Stream Performance to single-threaded integer results.

Geekbench Memory Performance results often make no sense, and FP, well it's hard to say what's going on, that denormal stuff Klimax mentions certainly is an issue that should be solved. I'll just say again what I told Klimax: the Android x86 version uses SSE and not x87. Here are the critical loops of Dot Product, both x86 and ARM:

c54d8: f3 0f 10 0c 97 movss (%edi,%edx,4),%xmm1
c54dd: f3 0f 59 0c 96 mulss (%esi,%edx,4),%xmm1
c54e2: 42 inc %edx
c54e3: f3 0f 58 c1 addss %xmm1,%xmm0
c54e7: 3b 55 f0 cmp -0x10(%ebp),%edx
c54ea: 75 ec jne c54d8
c54ec: 41 inc %ecx
c54ed: 3b 4d ec cmp -0x14(%ebp),%ecx
c54f0: 74 0a je c54fc
c54f2: 8b 50 28 mov 0x28(%eax),%edx
c54f5: 89 55 f0 mov %edx,-0x10(%ebp)
c54f8: 31 d2 xor %edx,%edx
c54fa: eb eb jmp c54e7


a42a8: eb06 0c03 add.w ip, r6, r3
a42ac: eddc 6a00 vldr s13, [ip]
a42b0: eb05 0c03 add.w ip, r5, r3
a42b4: ed9c 7a00 vldr s14, [ip]
a42b8: ee46 7a87 vmla.f32 s15, s13, s14
a42bc: 3101 adds r1, #1
a42be: 3304 adds r3, #4
a42c0: 42b9 cmp r1, r7
a42c2: d1f1 bne.n a42a8
a42c4: 3201 adds r2, #1
a42c6: 42a2 cmp r2, r4
a42c8: d003 beq.n a42d2
a42ca: 2300 movs r3, #0
a42cc: 6ac7 ldr r7, [r0, #44] ; 0x2c
a42ce: 4619 mov r1, r3
a42d0: e7f6 b.n a42c0


Both codes look similarly bad :-)
