More importantly, that number of models is the price that came crushing down with AMD pricing update last week, and now there are not many models above the $100 mark. Actually, there are none - a 65 nanometre attack in combination with conservative performance resulted in a great price offerings.
PowerColor's HD2400 line-up consists of four models, from the ultra-cheap HD2400 Pro DDR2, HD2400Pro SCS3 (Passive Edition) to more performance based HD2400XT with and without HDMI.2400Pro cards have GPU chips clocked at 525 MHz, while 256MB of DDR2-800 memory work at, you would never guess, 400 MHz DDR (800). XT parts work with both GPU and GDDR-3 memory clocked at high 700 MHz DDR. Sadly, AMD did a royal screw-up with the GPU's memory interface, so 2400 communicates with video memory using only 64-bit bus, yielding with bandwidth between 6.4-11.2GB/s.
HD2600 is a bit different. Four models feature three different memory standards, so some attention is in order. Entry-level HD2600Pro comes with 256MB of DDR2-800 memory, which works at the same clock as 2400Pro. HD2600Pro 512MB uses same memory type as the 256MB one, and GPU clock is the same at both cards - 600 MHz. Memory bandwidth is 12.8 GB/s in both cases.
In the HD2600XT world, things a re a bit more complicated, with HD2600XT 256MB GDDR-3 and HD2600XT 256MB GDDR-4. GPU clock is the same, but memory is waaay different - GDDR-3 memory is clocked at 700MHz DDR, while GDDR-4 card comes with 1.1 GHz DDR clock, or 2.2 GHz. Bandwidth difference between the two is pretty big - 22.4 GB/s versus 35.2 GB/s. To counter this, PowerColor placed non-reference cooler on GDDR-3 version, in order to offer greater overclocking potential.
Non-reference cooler could result in overclock of RV630 GPU into four-digit territory... or maybe not
Sadly, our review of HD2400/2600 boards will be late because we've had several of these boards stuck in Croatian customs for over a week now. Croatia is great for tourism, but do not expect an easy life if you're a freelance journalist - this will be sorted out with a move from Wild East to Mild West this coming fall. µ
