AMD Quad Core vs Six Core for video conversion

Last response: in CPUs

I have the following system that I built in 2010 -
Motherboard: GIGABYTE GA-MA785GMT-UD2H Micro ATX AMD Motherboard

CPU: AMD Athlon X4 620

Memory: G.SKILL 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Dual Channel Kit Desktop Memory

After the build I did a comparison on my dual core vs quad core for a video encode on a 5 minute test file to see time process difference:

HP laptop Pentium DualCore- 1.72 - 2g
ENCODING WITH PROFILE 'ff_tivo_hd'
encoding job completed: 00:35:52


AMD Quad Core 260 – 4gb
ENCODING WITH PROFILE 'ff_tivo_hd'
encoding job completed: 00:09:54

Would I see a big jump going from a AMD QC to an AMD 6 core?

If so which cpu and motherboard would be a good combo.

I just started reading about the 6core 1090t but not on any of the motherboards to go with a 6 core. Will be doing some more reading.

What application did you use to encode the video?

The above was handbrake -

The AMD 6 cores are beasts in H264 / AVC encoding. They compete well and beat many of the Intel processors in H264 video encoding, as well as being priced well. H264 encoding is one of the few processes that will truly utilize and max out all of a computers cores.

The more cores the better for H264 encoding.

So would there be a recommendation on a mb/cpu combo -

How much of an improvement in speed would one see.

From the Athlon X4 620 you will probably see a very significant jump; I'm sure you can find handbrake benchmarks for both but Passmark is a multi-threaded benchmark and has the 620 at 2986 and the 1100T at 6305... over double the performance. And the 1100T competes well with high end Intel offerings in handbrake, and is supported in your current motherboard.

IMO get the 1100T and 4 or 8GB of some good (Corsair ect) DDR3-1600... you will see a 80 to 90% performance increase.

Your question is pretty much answered but I figured I would chime in since I went from a 620 to a 1055t myself. The difference is what you would expect with handbrake with regards to scaling. (ie the two extra cores and additional clockspeed provide the expected performance increase)

So here is my complete setup on this machine as of now -
Motherboard: GIGABYTE GA-MA785GMT-UD2H Micro ATX AMD Motherboard

CPU Fan: XIGMATEK Intel Core i7 compatible Dark Knight

CPU: AMD Athlon X4 620

Memory: 8gb total - 2 sets of G.SKILL 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Dual Channel Kit Desktop Memory

Power Supply: BFG Tech GS-550 550W ATX12V T

OCZ 60gb ssd for windows 7

===============================
So I could keep the above and just by the AMD Phenom II X6 1100T Black Edition Thuban 3.3GHz -

Yes.

I do like DDR3-1600 or faster myself but really you will see almost all your performance increase come from the 1100T especially w/ 8gb ram... and it should be a goodly increase.

So is there any real big differences between the following -
1055t
1090t
1100t

AMD Phenom II X6 1100T 3300MHz 512KBx6 6MB Thuban

AMD Phenom II X6 1090T 3200MHz 512KBx6 6MB Thuban

AMD Phenom II X6 1055T 2800MHz 512KBx6 6MB Thuban

Alot of the readings say the 1100 isn't much better than the 1090?


Is one easier to overclock than the other?

The 1055t does not have an unlocked multiplier so it is harder to overclock. The 1090 and 1100 are the same with unlocked multipliers, besides clockspeed difference.

Based on the last prices I checked, the 1055t is the best deal, the 1090t is worth its price but the 1100t is overpriced compared to the 1090t for such a minor .1GHz bump in clockspeed (~3% theoretical performance increase) at stock.

Yeah I ended up purchasing the 1090t today so hopefully I will see it this week.

Thanks for all the info.

Will I still be safe with this as my cpu fan http://www.newegg.com/Product/Product.aspx?Item=N82E168...

While HB was running the cpu temps from CPUID Hardware Monitor sat at like 46 C.

Anyways A quick comparison of a file conversion in HB -

The file was .46 GB.

AMD Athlon X4 620 OC'd 3.2
Encoding job completed: 0:15:24

AMD Athlon 1090t X6 stock 3.2
encoding job completed: 0:08:30

This 2nd file was 2.19gb


AMD Athlon X4 620 OC'd 3.2
encoding job completed: 1:22:20

AMD Athlon 1090t X6 stock 3.2
encoding job completed: 0:48:20

This thread is old, but some of the speed boost you saw was due to the drive speed. Laptop typically have much slower drives than desktops.
