Review Roundup december 22 2010
Acer Aspire 7551G tested by legitreviews
Looking over the benchmarks it’s easy to see that the Acer Aspire 7551G was built to be a processing power house. The AMD Phenom II N930 quad core CPU was capable of handling any type of number crunching load
The LED backlight was consistent and provided a clear view. Left 4 Dead 2 and Starcraft II are both pretty dark games, the black levels throughout both titles were great!
The Acer Aspire 7551G performs like a desktop and has the ability to be used on the go. Those in the market for an affordable gaming laptop should keep the 7551G on their short list.
Acer Aspire 5551G-4591 tested by pcper
The Acer Aspire AS5551G-4591 isn’t exactly a brand new design. The main difference between this and the earlier AS5740G is the processor, which is an AMD Turion II instead of Intel’s Core i3.
he trackpad surface is large enough as well. However, the trackpad buttons are a one-piece rocker design. This creates a non-functional dead zone in the middle of the trackpad and results in button feel that can be generously described as squishy.
As you’d expect, the Acer Aspire 5551G-4591 includes a TN panel display with a resolution of 1366×768. This display size and resolution is synonymous with mediocrity. The contrast, black levels and white saturation are all about average.
Sony VAIO VPCZ137GX/S tested by techreviewsource
The Sony VAIO VPCZ137GX/S is a 13.1-inch portable notebook that has a fantastic design and appeal. It also features an Intel dual-core i5-460M CPU clocked at 2.53GHz, 4GB of RAM and a 256GB solid-state hard drive.
It’s a little bit of a disappointment that the screen is only 720p HD resolution and not full 1080p HD considering the price, but it looks great nonetheless.
Performance with the Sony VAIO VPCZ137GX/S is outstanding and hopefully so as again, the cost is rather steep. Mundane computer tasks performed with speedy quickness, but even more intensive tasks, like video encoding, worked quicker than most other models, so you’re definitely getting your money’s worth.
ASUS M4A88T-I Deluxe tested by xbitlabs
In fact, we have already seen examples like that when we discussed miniature LGA 1156 mainboards from Zotac (Zotac H55-ITX WiFi) and Gigabyte (Gigabyte GA-H55N-USB3). But Asus M4A88T-I Deluxe is a truly unique product because it is the first multi-functional Mini-ITX Socket AM3 platform in the market.
There is another unique feature right next to the PCI Express x16 slot: it is a daughter card with a WiFi controller on it. In this case we have an 802.11n solution based on Ralink chipset and radio module. Unfortunately, this card connects to the mainboard via a modified USB port instead of a common connector, so you won’t be able to replace it with anything else without additional modifications.
Overall, Asus engineers have definitely succeeded in designing a small Socket AM3 mainboard with rich functionality. It is for a reason that this mainboard is part of the Deluxe series, which includes only the solutions with the richest functionality and features.
Samsung 470 Series 256GB SSD tested by pcper
Samsung’s new 470 Series is absolutely a step above the previous generation. Sequential write speeds are among the fastest we’ve tested. The new controller enables a significant random read IOPS boost at higher queue depths. While our tests showed great improvements in many areas, further analysis of the results revealed a chink in the armor – hitting the 470 with simultaneous reads and writes caused both operations to suffer greatly once the write cache was full, dropping performance to HDD-class speeds. Copying large or even smaller files from/to the drive took longer than we’d hoped to see from this new unit.
- CPU : Intel Core i7 920
- Graphics Card : BFG Geforce 8400 GS 512MB PCI
- Mainboard : Asus P6T
- PSU : Corsair CMPSU-650TX
- RAM : Corsair Dominator 3x2GB DDR3-1600Mhz
- SSD : G.Skill 32GB SLC
Palit GTX 570 Sonic Platinum tested by tbreak
This vedeo card has a 9% Core and Shader clock, and 5% Memory clock increase when compared to the reference model. The price increase is almost 10% compared to normal GTX 570 (AED 1,490) but still 21% cheaper than a GTX 580 (AED 1,989). Let’s see if the performance holds up to those numbers. Before that however, I will get down to the other important improvement to the Palit GTX 570 Sonic Platinum: the new cooling solution.
Also, the new thermal solution helps keep temperatures low as well, with idle temperatures hovering around 41°C whereas full load goes up to 79°C.
In conclusion I will say that Palit’s GTX 570 Sonic Platinum is one hell of an overclocked card, with performance boost high enough to touch the heels of the GTX 580.
EVGA GeForce GTX 570 Superclocked tested by hardwaresecrets
EVGA has three lines of overclocked video cards, listed from the lower overclocking level to the highest: Superclocked (SC), Super Superclocked (SSC), and For The Win Edition (FTW). So far EVGA released only an SC model for the GeForce GTX 570, with an 8.9% overclocking on the graphics chip and a tiny 2.6% overclocking on the memory.
The EVGA GeForce GTX 570 and the Radeon HD 6970 achieve similar performance on Call of Duty 4, Aliens vs. Predator and 3DMark 11 (sometimes one was a little bit faster, sometimes the other, but the difference was not significant). However, on the other three games, the EVGA GeForce GTX 570 Superclocked presented a huge advantage: up to 21% faster on Crysis Warhead, up to 28% faster on Far Cry 2, and up to 55% faster on Lost Planet 2.
