Looking for a laptop

[spectacular.ak]

I would like to know that for a laptop which characteristic is more important...Core or Operating frequency Briefly, I have to choice Core i7 7500 and A12-9720, which one should I choose?

The i7 will be quite a bit faster. You can't tell anything about how fast a CPU is just by looking at the speed or number of cores, you need to actually look at benchmarks for the CPU.

Depends what you need the laptop for. A processor with fewer cores but a higher base clock/turbo generally will out perform any 2 core mobile CPU (2/4 cores-threads IIRC).

The 7500 and similar cpu's run on much less power than something such as a 7300/7700hq, produce less heat, and are more suitable for all around usage (gaming, media editing, general use).

Now that being said you shouldn't have an issue playing many games on the 7500 but if it's gaming you're most interested in I'd suggest something else.

There's also laptops with new 8th gen intel chips which doubles the cores/threads (4/8) which are very good (currently on an i7-8550u) and can come in a variety of small to normal form factors/dgpu's etc.

If you could specify what your budget is and what use you want the laptop for I'll post some suggestions.

What are your needs and expectations for the laptop you want to buy?

For now, I recommend you avoid AMD APUs in laptops... at least until laptops are available with AMD's Ryzen mobile APUs like the Ryzen 5 2500u and Ryzen 7 2700u. The A12-9720P APU is based a design older and far weaker than the AMD's Ryzen architecture. The A12-9720P is about equal to a 4th or 5th general Core i3 CPU.

The A12's Radeon R7 (Bristol Ridge) integrated graphics core is roughly equal to a nVidia 930m which makes it more powerful than the Intel HD 620 graphics core. The Intel HD 620 is a little less powerful than the nVidia 920m.

Both Ryzen 5 2500u and 7 2700u have 4 cores and each core is able to process 2 threads of instructions. In terms of performance, the Ryzen 5 2500u is expected to compete against the quad core Intel i5-8250u while the Ryzen 7 2700u is expected to compete against the quad core Intel i7-8550u.

The Ryzen 5 2500u will have the RX Vega 8 integrated graphics core which is estimated to be about equal to a nVidia 940m. The Ryzen 7 2700u will have the RX Vega 10 integrated graphics core which is estimated to be about equal to a nVidia 945m.


Having said the above, the laptop's using Ryzen APUs will probably be priced similarly to laptops with Intel CPUs that are of comparable processor performance.

Thank you for all responses, In fact, I want to choose an engineering laptop.I have seen an HP laptop(cd099nia) with A12 core and so many corei7 laptops.It becomes a question for me that why they use an A12 core for their laptop and maybe it has an especial character rather that corei7, although A12 has some special features.

In almost all cases vendors use AMD CPUs for cost savings or possibly on-board video speed vs Intel. Given all other things being equal, an i7 laptop will be more expensive.
