Reviews for the Sony Vaio VGN-SR420J/B
Source: Comp Reviews
Archive.org versionSony'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.
T6500:
Entry level Penryn based dual-core CPU with a small 2MB level 2 cache and FSB800. Similar to the T6570 but without VT-x.

There are hardly any tablets in this display size range anymore. For subnotebooks, on the other hand, it is the standard format.
The advantage of subnotebooks is that the entire laptop can be small and therefore easily portable. The smaller display also has the advantage of requiring less power, which further improves battery life and thus mobility. The disadvantage is that reading texts is more strenuous on the eyes. High resolutions are more likely to be found in standard laptops.

80%: This rating is not earth-shattering. This rating must actually be seen as average, since there are about as many devices with worse ratings as better ones. A purchase recommendation can only be seen with a lot of goodwill, unless it is about websites that generally rate strictly.
