Radeon HD 4890 vs GeForce GTX 275

Gigabyte Radeon HD 4890 (GV-R489-1GH-B)

Manufacturer: Gigabyte
UK Price (as reviewed): £212.98 (inc. VAT)
US Price (as reviewed): Unknown

Core Clock: 850MHz
Memory Clock: 3,900MHz (effective)
Memory: 1GB GDDR5
Warranty: Three years parts and labour

Again, we only got a bare card from Gigabyte so here's a reference box shot below. Inside the box there is:

• Active DVI to HDMI adapter (with audio passthrough)
  
• DVI to VGA adapter
  
• Two Molex to 6-pin PCI-Express power adapter
  
• CrossFire bridge
  
• Component breakout cable
  
• Composite adapter

Again nothing like an Asus mouse mat (if you care) or HDMI cable, but at least there is the general array of connectivity for all manor of hardware included. Gigabyte clocks its card to stock speeds and uses a reference design like the rest with a simple sticker to differentiate itself. With a three year warranty, it matches the Asus and exceeds that of PowerColor by an extra year in this department.

US Price (as reviewed): Unknown, $249.99 (ex. Tax) for stock speed card

HIS dropped us its Turbo version of the Radeon HD 4890, with the GPU clocked to 900MHz and the memory to 4,000MHz - a 50MHz and 100MHz overclock from stock speeds respectively. The price hike over the stock version is as yet unknown, although it should only be £5-10 if HIS aims to keep in line with other AMD partners such as PowerColor. Inside the box there is:

• Active DVI to HDMI adapter (with audio passthrough)
  
• DVI to VGA adapter
  
• Molex to 6-pin PCI-Express power adapter
  
• CrossFire bridge
  
• Component breakout cable
  
• Composite adapter
  
• Software disk and paper manual
