Why is the heterogeneous performance of APUs much better than that of ordinary processors?

The theory is very powerful,The main reason is that the display core integrated by the APU is relatively advanced,Theoretically higher than the current ordinary entry-level independent display core,Therefore, the theoretical test results are very good,For example3D MARKThe results are very ideal,More than the low-end entry independent display HD5450A lot,This has a very strong theoretical basis for boasting that the APU is very good。 But the actual game test is not the case,Although the graphics performance is the most powerful integrated graphics card at present,It can also be said that it is more than a little more powerful than other integrated graphics,But if it is compared with an entry graphics card like HD5450, it is still much worse。 The reason is that although the APU integrates the powerful HD6000 series core, the video memory is only shared memory, and the fastest memory DDR3 1666 on the market is also much worse than the video memory GDDR5.

In addition, the width of the video memory bit is not as good as that of the independent display. There is also a very important reason, AMD's optimization is not in place, and the cost performance is not high. As can be seen from the fact that the actual game is not as good as the HD5400 series GPU, it can be seen that AMD's software optimization still has a long way to go.

Addendum: Landlord, please look at the picture carefully. The A8 in the yellow box in the picture is already in use"Hybrid acceleration". (a8-3500m cpu & gpu opencl)

It depends on the use.

The GPU graphics part of the APU is equivalent to the mid-range, and the CPU part is somewhere between the Celeron and the Pentium. Therefore, the APU is more suitable for low-end machines that are very cheap. Especially if you play games more than 80% of the time, but don't want to spend more money on a discrete display.

In terms of heterogeneous computing, it is theoretically good, but after the real test, the i5 only uses OpenCL to run on the dual-core CPU, which is better than the A8 on the "100 cores", see the evaluation in the attached figure. Note that Intel does not provide OpenCL core graphics interface, so the i5 core graphics do not use OpenCL. So theory is one thing, implementation is another.

At least the APU is not optimized well.

There's too much to talk about upstairs, and it's just that it's just an ideal, and you need to use software to achieve it. It's like a 64-bit system is faster than a 32-bit system, and I haven't seen it in years. What's more, this so-called heterogeneous performance actually has a lot to do with graphics.

If it's just office software, the CPU is the deciding factor.

Dell 15R -668 recommended

i5 2410 4G 500G GT525 1G Discrete Graphics Camera Bluetooth The market price is around 4600.

APU's products have not been specifically tested, I don't know if the performance is good or not, what is advertised, I don't believe it, or the data has the final say.

APU is not as good as i5,This has been tested,The graphics card of the nuclear display is not good,Use the latter for the independent display。
