Reviews for the Sony Vaio VGN-SR420J/B

80% Sony VAIO VGN-SR420J/B 13.3-inch Ultraportable Laptop PC
Source: Comp Reviews
Sony's VGN-SR420J/B is an update to their low cost 13-inch ultraportable that does some things right but suffers from older technology and too much software clutter. The graphics are the key selling point of the laptop with an excellent LED backlit display and a dedicated graphics processor, a rarity in this market class. Sony also provides a wide range of peripheral ports including FireWire and an ExpressCard slot. Its too bad that Sony didn't see the need to also upgrade the memory or reduce the amount of software that hampers performance.

ATI Mobility Radeon HD 4570: Lower middle-class GPU that features a low shader count and a 64 Bit memory bus but a high clock speed. Similar to the desktop Radeon 4550. Supports Avivo HD and DirectX 10.1.

Only some 3D games with very low demands are playable with these cards.

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.

13.3":

Above all, this display size is used for subnotebooks, ultrabooks and convertibles. For all three types, this size is quite large. The biggest variety of subnotebooks is represented with this size.

Large display-sizes allow higher resolutions. So, details like letters are bigger. On the other hand, the power consumption is lower with small screen diagonals and the devices are smaller, more lightweight and cheaper.

2 kg:

This weight is typical for very big tablets, subnotebooks, ultrabooks and convertibles with a 11-13 inch display-diagonal.

From 2014, Sony has reduced the production of Vaio laptops and finally discontinued them. Sony is still present in the smartphone and tablet market, yet not among the Top 5 manufacturers.

80%: This rating is not convincing. The laptop is evaluated below average, this is not really a recommendation for purchase.
