Sony may be best known for its ultraportable notebooks but it isn’t afraid to take a few chances at the other end of the scale, as this 3.8kg desktop replacement can attest to. If you must have a desktop replacement with all the latest bells and whistles in place, and have the money to support your demands, this is a great notebook. True, you’re not interested in its portability, as that’s rather limited, but everything else you want from a high-end notebook is here – enjoy!

Comment
NVIDIA GeForce Go 7600: The NVIDIA GeForce Go 7600 is a middle class video card of the 7000 series and suited for games of the year 2006. The performance is very similar to ATI X1600 / X1700. Compared to the desktop 7600 it is clearly slower.
Lower end of Graphics Cards for users who want to play games. New games should run on these cards, but only with decreased details and mediocre resolution.
>> Further information can be found in our Comparison of Mobile Graphics Cards and the corresponding Benchmark List.
Intel Core 2 Duo: This is the Core Duo and Core Solo successor with a longer pipeline and 5-20% more speed without more power consumption. As an addition to the Core Duo design there exists a fourth decoder, an amplified SSE-unit and an additional arithmetical logical unit (ALU).
The Core 2 Duo for laptops is identical to the desktop Core 2 Duo processors but the notebook-processors work with lower voltages (0.95 to 1188 Volt) and a lower Frontside bus clock (1066 vs 667 MHz). The performance of equally clocked notebooks is 20-25% lower than Desktop PCs because of the lower Frontside bus clock and the slower hard disks.
T7200:

17.1": Nowadays, meanwhile the 17 inch display size is a more frequently offered standard format for desktop-replacements. 17 inch laptops are built only in 16:10 format.
The DTR-Laptops can't be carried easily, need much current, but on the other side texts can be read easily and high resolutions are no problem. DTR mainly are intended for stationary usage on desks, where the weight and the energy need are unimportant.
>> To find out how fine a display is, see our DPI List.
3.8 kg: This laptop is heavy below average, compared with the average of notebooks. Therefore especially desktop replacements fit in this class of weight.
Sony: Sony is a notebook manufacturer of medium size according international market shares. There exist a lot of reviews about Sony notebooks. The total ratings and price/value ratings are good above average.
83.2%: This rating is to be considered as average, because the amount of notebooks with better ratings is about equal like the amount with worse ratings.
