Mid Range Graphics Card CPU scaling

For mid-range cards we've got three from ATI and one from NVIDIA; as we've discovered in previous Half Life 2 articles, NVIDIA's last-generation mid-range cards are only reasonable performers in DirectX 8 mode, and we are conducting a fully DX9 comparison here so that excludes all of them. From ATI we've got the Radeon 9700 Pro, Radeon 9800 Pro and Radeon X700 Pro. We've also included the NVIDIA GeForce 6600GT, which as you will remember from our previous articles, performs very similarly to the GeForce 6800 non-ultra under Half Life 2.

Our mid-range tests were conducted at 1280 x 1024, the target resolution for most mid-range cards.

If you've got any of ATI's mid-range GPUs, you're stuck with severely diminishing returns after about 1.4 - 1.6GHz on the Athlon 64 (< 2800+ range). The GeForce 6600GT is far less GPU bound at 1280 x 1024 (and even at 1024 x 768 although not depicted here), and thus scales relatively well.

    NF4 will not be supporting AGP bud, sorry, its PCI-E from here on out.

    Ill backup the thought of putting some T-bred cores in there. My OC'd XP2600 333 w\ modded 9500 radeon system ran HL2 very well. I would have liked it to have been better, but it is not worth upgrading yet. Reply

    Hehehe.. I'll fifteenth the "Please include an AXP3200+" sentiment. Personally, I'd rather see one or two AXPs included than a complete list of athlon64s.. You can generally extrapolate the performance of a given CPU if you are given two other CPUs with the same cache/FSB/core. I know that my Mobile barton handled the game fine, but I'd like to know how far behind a cheap A64 it really is. Reply

    "Our standard 2-2-2-10 memory does actually offer reasonable performance benefits in Half Life 2 compared to DDR400 with higher timings such as 3-3-3-10 or the unrealistically high 3-6-6-10."

    Reasonable performance benefits? decent 2.5-3-3-10 ram can be found cheap nowdays (http://www.newegg.com/app/ViewProductDesc.asp?desc... and compared to the oczrev2 and other $200+ modules is at least $60 cheaper, in some case as much as $100 cheaper. The 2-2-2 is only 2% faster than the 3-3-3, so does that extra $60+ really offer "reasonable performance benefits"?

    #13... I wouldn't call that an error, I'd call that a difference in opinion. :) Reply

    There seems to be an error on page 4- "Almost all DDR400 these days is CAS 2 memory, but older memory may have a higher CAS latency..."

    Shouldn't it say "Almost all DDR400 tested by AnandTech is premium CAS 2 memory, but CAS 2.5 and CAS 3 are more common..."

    What about SLI configs? I think people looking SLI for an option may want a better idea how their CPU choice affects the dual GPU choice. Can you add SLI'd 6600GT, 6800GT, 6800 Ultra benches to the tables at the end of your article? Reply

    Yeah, although probably unrealistic, tossing AXP's into a "low end range" comparison along side would help some people. Overall, great article! Reply

    I liked the Ram latency and 64-bit/128-bit test. But I'm wondering how would 2.5 Cas would perform? Makes sense to list it since a lot of value named brand ram modules come with 2.5 CAS. I would think it would perform in-between the two, but I'm having the slightest inkling that 2.5 CAS and 2.0 CAS will perform the same.


    Can't wait to hear about multithreaded games for dual core CPUs.

    Well we can look at the other HL2 articles cause there's an XP3200 in those... but... this being a CPU oriented article I thought it would be nice to have that CPU included. Possibly even an XP3000 so we can get an idea for how it scales so I can estimate how my 2.48 GHz Mobile AXP compares. Reply
