Performance of AMD processors.

HP Pavilion G6-2302AX

Processor: AMD Dual Core A4 4300M-2.5Ghz,4MB Cache, Turbo Boost upto 2.8Ghz
Chipset: AMD A70M
Memory: 4 GB DDR3
Memory Upgradeable: Up to 8 GB
Hard Disk: 500 GB SATA (5400 rpm)
Operating System: Windows 8
Graphic Processor: 1 GB DDR3 AMD Radeon HD 7640G/7670M Dual GPU

This laptop costs me Rs. 29500.

According to me, advantages of this laptop over Samsung 3 series NP305E5Z-S01IN are:-
- Better processor.
- Higher graphic card.
- Installed genuine Windows 8.
- Also, HP is more trust worthy than Samsung.

Basically, I will be working on CATIA and other CAD softwares on this laptop. They require higher CPU usage and better graphics. I won't play games on it. I will use it for office purpose, watching movies, internet surfing, etc.

Will it be able to run softwares like CATIA, ANSYS, UGX ? I will be using these softwares on beginner level, not professional. But I need atleast 3 GB RAM and 1 GB graphics card.

But, the thing that's bothering is both the laptops have AMD processors. I've gone through reviews and comparison of AMD and Intel processors. Although, AMD processors are cheaper and have better graphics than Intel. Durability and processing speed of Intel processors are better.
Also, the shop keepers are suggesting me not to go for AMD because its not reliable and durable. They said "Don't blame us if you face any problem in future."

I am an Indian. Does it have to do anything with inferior quality of product OR difference in product performance due to variable weather condition in our country?

 

Yeah; AMD cpu/apu's - hotter, more power (battery) hungry and perform markedly below Intel solutions.

Not a good choice imo for notebooks for any usage pattern.

 

Check out this thread on AMD processors:

Reliability of the chip itself wouldn't be my concern; for your usages, I would however be concerned about performance. Intel CPUs are a good clip faster than AMD CPUs, though they cost more. Fill out this questionnaire and post it in the What Notebook Should I Buy forum, and we'll help you find the right notebook.

 

From personal experience, ANSYS (whatever package you're going to buy, workbench, fluent, polyflow...?) and other FEM software tend to hammer the CPU hard and even stuff that seems simple to calculate can take quite a bit of time (and RAM) depending on what you do. Fluid mechanics, especially turbulent flow, tend to be resource hogs and the extra performance afforded by an Intel mobile quad core can be invaluable.

There is somewhat of a lack of benchmarks for the AMD APUs, but that A4 is likely slower than a first gen core i5 and a quad core i7 mobile will be 2 to 3 times faster at least.

 

Chips are chips are chips, so just being in India won't affect the quality of the chip. They're all from Costa Rica or wherever the chip fab plants are anyway; they just get shipped out to India and the other markets.

Normally, I'd say "CPU doesn't matter" for most users, but with CAD and other engineering/scientific software packages, it would be better to get the highest Intel CPU you could get (within reason... I wouldn't get anything above an i7-x720QM/i7-x760QM personally).

 

I agree, that is unless you were to crunch numbers (or render or whatever it is you do that is CPU intensive) all day. In that case every minute of time saved counts, but otherwise, saving a few minutes per simulation won't really matter.

 

Hell, even some CompSci topics can bring a CPU to its knees. I wrote a statistics program in C not too long ago which implemented bubble sorting (inefficient, but simple) and running that program with a .txt of 200,000 numbers plus takes a good 20 minutes or so on my workstation.

(Only wrote the program for fun, though, so no worries)

 

Good ol' bubble sorting, terribly inefficient as you said, but rather robust and one of the first things you see in basic programming classes. Speaking of hammering CPUs, try a few days non-stop on a 6-core CPU with RAM usage over 50GB. My Kingdom for a cluster. I gotta say the if KCETech1 passes by she'll put us all to shame with how resource intensive her workload is.

 

50GB of RAM...? You and KCETech1 boggle my mind with all that RAM.

And I thought that 12GB was stupid-large...

 

Even went through a numerical method class? I had to use a direct solver instead of an iterative solver and that takes ~3-4x the amount of memory an iterative solver would. Try solving a system that has a few million equations using LU factorization, that eats memory ridiculously fast.

 

Durability of AMD parts is the same as Intel parts. And being in India has nothing to do with quality or durability, it is the same anywhere in the world.

 

Being in India makes a difference if it will be used in non-air conditioned spaces... and even at the wallet for the work performed per time period.

If it is run hotter than an Intel CPU for longer periods of time... then it will be more likely to fail also because of the increased stress...

Yeah, durability is not the same at all - if all factors are properly taken into consideration.

 

Eh, I'm assuming that it's being used in some form of an air-conditioned room. Sure, it'll die faster if left in bad conditions that are found outside, but it'd do the same down here in the American South if left outside too.

 

You know that India, much like China and the US, has a variety of climates, right? Do you have any evidence at all that climate has an impact on the wear and tear on a laptop? You are actually saying that if I live in southern Florida, my laptop on average will last less time than if I live in Maine? Are you joking?

You say heat leads to some sort of nebulous "increased stress?" Aside from the defective Nvidia chips from five or so years ago, what other products from them, AMD, or Intel have had heat-related failures? None. Even people who overclock their processors as high as they can go don't have these issues. What is the worst that can happen? Your computer starts throttling and you need to clean the dust out of the heatsink?

You are just hypothesizing and making up phony baloney.

 

Obviously you know how cpu's work better than I do.

Make up your own theories of why overclocked cpu's die decades faster than ones left at stock clocks (and normal operating temps).
