Difference between three seemingly similar Toshiba satellite 17.3" laptops

[ap8330]

Laptop 1) Toshiba - Satellite 17.3" Laptop - AMD A6-Series - 6GB Memory - 750GB Hard Drive - Jet Black (Model# C75DB7230)

- AMD A6 (2.4GHz)
- 6GB RAM
- 750GB memory
- AMD Radeon R4 (read that this was practically a tablet graphics card?)
- ~$500
--------------------------------------------------------------------------------------

Laptop 2) Toshiba - Satellite 17.3" Laptop - AMD A8-Series - 6GB Memory - 750GB Hard Drive - Jet Black (Model# C75D-B7100)

- AMD A8 (2GHz)
- 6GB RAM
- 750GB memory
- AMD Radeon R5
- ~$400
--------------------------------------------------------------------------------------

Laptop 3) Toshiba Jet Black 17.3" Satellite C75D-B7215 Laptop PC with AMD A8-6410 Quad-Core Processor, 8GB Memory, 1TB Hard Drive and Windows 8.1 (Model# C75D-B7215)

- AMD A8 (2.40GHz)
- 8GB RAM
- 1TB memory
- AMD Radeon R4

--------------------------------------------------------------------------------------

Other than the RAM and storage differences, what are the major differences between each laptop and how do they really compare against each other?
- A6 vs A8
- R4 vs R5
- 2 more GB of RAM

I am taking into consideration that different places have different prices. Also, if there are any laptops that you would recommend within the $400-500 price range, please let me know.

Thank you for your time!

Laptop #3 is the clear winner.

The A8 is the better part as it is quad core, but the A6 is dual core.

6 vs 8 GB of RAM will not much of a difference, but more is better.

Laptop #2 and #3 are very similar since both have the same AMD APU, the A8-6410. The A8-6410 has a clockspeed of 2.0GHz, but can overclock itself to 2.4GHz under the right conditions. Walmart obviously decided to advertise the higher clockspeed, additionally, they also incorrectly stated it has a Radeon R4 graphics core. The A8-6410 APU has the Radeon R5 graphics core which is more powerful than the Radeon R4.

The $100 difference between Laptops #2 & #3 boils down to an extra 2GB of RAM and 250GB of storage space. That is kinda steep. If the extra 250GB is not that big of a deal, but you want to have 8GB of RAM instead of only 6GB, then you can purchase the following 4GB stick of RAM for $30 and install it into Laptop #2.
