Test System Components And Software
CPU #1: Athlon 64 X2 4800+ @ 2.4 GHz
We chose the Athlon X2 4800+ because it’s fairly powerful, but can be found for fairly cheap. At the time of writing, a 4800+ can be found for about $50. This is a good price for a solidly-performing dual-core CPU in an HTPC, and we used it for almost all of our benchmarks except the ones performed to test the single-core Sempron.
CPU #2: Sempron 3200+ @ 1.8 GHz
The Sempron is a much slower single-core CPU running at 1.8 GHz compared to the 4800+’s 2.4 GHz. It will provide us with a good idea of just how much CPU is required for 1080p playback.
Memory: 1GB Patriot PC2-6400, 1x 1024 MB, CAS 5.0-5-5-16
We went with a single gigabyte of memory because we wanted to put these motherboards through a gritty real-world low-cost scenario. In many cases, integrated graphics is the only option for folks on a limited budget, so the amount of memory should reflect that model.
Operating System: Vista Ultimate 32-bit
We use the 32-bit version of Microsoft’s Windows Vista because the OS is inevitably going to become the standard operating system, regardless of how we feel about it. Note that even though we used Vista Ultimate, video playback performance will be identical across all 32-bit Vista installations whether it’s Vista Home, Professional, Ultimate—all 32-bit Vista versions share the same core and driver base.
780G Motherboard: Gigabyte GA-MA78GM-S2H
The 780G-based motherboard we used for testing was Gigabyte’s GA-MA78GM-S2H, which offers both HDMI and DVI digital outputs, as well as an analog VGA. Testing demonstrated that the DVI output was curiously devoid of HDCP compliance, by the way.
Other features include dual channel DDR2 1066 memory support, one PCI Express 16x slot, one PCI Express x1 slot, two PCI slots, onboard 8-channel audio, Gigabit Ethernet, 4 USB ports, a FireWire port, and an eSATA port.
The motherboard, complete with integrated graphics chip, can be found online for less than $85—a very reasonable price for a motherboard with fast integrated video, but there are some cheaper 780G motherboards out there. It is notable that Gigabyte also produces an MCP78S-based motherboard, the GA-M78SM-S2H.
MCP78S Motherboard: ECS GF8200A Black Edition
We used ECS’ GF8200A motherboard to represent the MCP78S chipset. Its features are very similar to the competing 780G chipset right down to its dual-channel DDR2-1066 memory support, single PCI Express 16x slot, one PCI Express x1 slot, three PCI slots, onboard 8-channel audio, Gigabit Ethernet, six USB ports, and an eSATA port. The main differentiating feature is that the GF8200A has no DVI output., while the GA-MA78GM-S2H does.
Another noteworthy feature of the MCP78S chipset is Nvidia’s Hybrid Power feature that enables the motherboard to shut down a compatible discrete graphics card when it’s not under load and instead use the integrated GPU to save power.
The GF8200A can be found online for $70. For a motherboard with excellent integrated graphics, this is an absolute steal. As with Gigabyte, we’ll note that ECS also manufactures motherboards based on both AMD and Nvidia chipsets. Its 780G-based motherboard is the A780GM-A.
Discrete Graphics Card: Radeon 2400 PRO
We’ll compare the integrated Radeon HD 3200 to it’s discrete sibling, the Radeon 2400 PRO. Even though it is a discrete card, its hardware specifications are identical to the integrated Radeon HD 3200.
Discrete Graphics Card: GeForce 8400 GS
We’ll compare the integrated GeForce 8200 to it’s larger brother, the GeForce 8400 GS. This card has the same number of universal shaders as the integrated 8200, but twice the number of ROPs and texture units.
Blu-Ray Drive: Lite-On DX-401S External
Lite-On’s external solution is an ideal portable Blu-ray drive for folks who want to watch high-def content on their home-theater PCs and easily move the unit to a laptop in another room on a whim. It also happens to be ideal for our Blu-ray playback testing because its mobility is appreciated between our test systems, and it demonstrates that good Blu-ray playback doesn’t require SATA disk transfer speeds.
The unit is quite attractive and is reminiscent of a Nintendo Wii. It can even be placed on it’s side on a Wii-like stand. The black-and-white styling is aesthetically clever and pretty much goes with anything.
Display: Samsung 245BW 24” LCD monitor
Our trusty Samsung 245BW isn’t the most advanced monitor available, but it’s a good deal for the price. Typical of many aging LCDs, HDCP compliance is provided over the DVI input and there is no HDMI input available. With the 780G motherboard lacking HDCP support on it’s DVI output and the GF8200A having no DVI option at all, we were forced to find some creative workarounds.
HDCP Decrypter: Slysoft AnyDVD HD
AnyDVD HD is a software solution that will decrypt Blu-Ray and HD DVD movie disks over a digital connection, eliminating the need for an HDCP-compliant graphics card or monitor. The software was absolutely invaluable in a playback scenario we encountered later in the review where we were playing back a Blu-ray over a DVI connection that wasn’t HDCP-enabled.
Cyberlink PowerDVD Ultra
Cyberlink’s PowerDVD Ultra is one of a very small handful of software video players that can play back protected HD content from HD DVD and Blu-ray sources. It’s an excellent player, although on rare occasions it seems we still encounter a few HD playback bugs, usually in congruence with the video driver. Even with these limitations, it’s the most stable software HD player we’ve used to date.
It would have been nice to see a 780G board with sideport memory in this test (e.g. GA-MA78GPM-DS2H) as this is meant to improve performance.
Im shocked that they have chosen to use 1 dimm configuration.
both motherboards, due to the nature of the AMD platform, support dualo channel configuration to increase memory bandwidth, which would also have been enjoyed by the intergrated GPU's.
I know toms argue that the likly configuration in this set up would be 1GB, but if u were a self builder you would choose 2x512 to maximise the platforms abilitys.
not good imho.
^^
Or alternatively this was a test to see how well everything runs without dual channel support. You'd be surprised at the number of shop-bought systems that only have 1 RAM chip in them.
Nice article, I had been looking into using PureVideo with the GFX card I just bought.
Just one criticism: Using red and green lines for the charts on page 7 made it nearly impossible for me to tell which line was for which card, as I have deuteranomaly, which is a mild form of red-green color blindness. You should use slightly different colors for charts like that.
