System Benchmarks: HDxPRT 2010 / PCMark Vantage

System Benchmarks: HDxPRT 2010 / PCMark Vantage



HDxPRT 2010


Intel High Definition Experience and Performance Ratings Test 2010

HDxPRT 2010, otherwise known as the Intel High Definition Experience and Performance Ratings Test 2010, is a new platform evaluation tool for measuring digital media experience. HDxPRT evaluates the capabilities of a media PC using real world usage scenarios and popular media applications. The benchmark's results are illustrated in the Create HD Score, which represents the overall digital media creation performance of a test system.

HDxPRT 2009 workloads are based on usages performed with popular programs, like Adobe Flash Player 10.1, Adobe Photoshop Elements 8.0, Apple iTunes 9.x, Cyberlink PowerDVD 9, DivX Pro Codec 6.8.5, HDRsoft Photomatix 3, HDR PhotoStudio 2.x, and Windows Media Player 11.

PCMark Vantage x64


PCMark Vantage Advanced 64-bit Edition (1.0.2.0)
PCMark Suite / Default Settings
Comparison: Generated Score

The main focus of our General Tasks category lies with the most recent installment of the PCMark series, Vantage. While still classified under the description of a Synthetic benchmark, PCMark Vantage uses many of Vista's (Note - Vantage is Vista-only) built-in programs and features along with its own tests, so it is "real-world" applicable in regards to CPU performance. The following is a general list of the tests in the PCMark suite, very much in line with tasks of an average user: Data encryption, Data compression, CPU image manipulation (compression/decompression/resize), Audio transcoding, Video transcoding, Text editing, Web page rendering, Windows Mail, Windows Contacts, and CPU game test.

System Benchmarks: LFE / Photoshop CS4 / x264 HD

System Benchmarks: LFE / Photoshop CS4 / x264 HD



Lame Front End


Lame Front End v1.0 is a single-threaded application, which means that it only utilizes a single processor core. This will obviously limit performance but it will allow us to gauge a processor's single-threaded performance as well as test any turbo feature that it might have. We will be encoding a WAV rip of Santana’s Supernatural album and converting it to MP3 using the highest fidelity VBR 0 quality preset.

chart16.jpg


Photoshop CS4


For the image editing portion of this review, we will use Photoshop CS4 in coordination with Driver Heaven’s Photoshop Benchmark V3, which is an excellent test of CPU power and memory bandwidth. This is a scripted benchmark that individually applies 15 different filters to a 109MB JPEG, and uses Photoshop’s built-in timing feature to provide a result at each test stage. Then it’s simply a matter of adding up the 15 results to reach the final figure.

x264 HD Benchmark


x264 HD Benchmark v1.0
Test: MPEG-2 HD 720P Video Clip Conversion to x264
DVD Video Length: 30 Seconds
Comparison: FPS of Second Pass

x264 is quickly becoming the new codec of choice for encoding a growing number of H.264/MPEG-4 AVC videos. Think of it as the new Divx of HD and you can understand why we felt it critical to include. Tech Arp's recent development of the x264 HD Benchmark takes a 30 second HD video clip and encodes it into the x264 codec with the intention of little to no quality loss. The test is measured using the average frames per second achieved during encoding, which scales with processor speed and efficiency. The benchmark also allows the use of multi-core processors so it gives a very accurate depiction of what to expect when using encoding application on a typical full length video.

Filtering: 4X MSAA / Anisotropic 8X
Graphic Settings: High
Shader Detail: Very High
Test 1: HWC Custom Timedemo
Comparison: FPS (Frames per Second)

Left 4 Dead is the latest disorienting, fast-paced zombie apocalypse mega-hit from Valve. L4D uses the latest version of the Source engine with enhancements such as multi-core processor support and physics-based animation. We test here at 1680x1050 with in-game details set to their highest levels, with MSAA 4X and AA 8X. For benching, we used a pre-recorded 20 minute timedemo taken on the No Mercy campaign during The Apartments mission.

Valve Particle Simulation Benchmark


Valve Particle Simulation Benchmark
Default
Comparison: Particle Performance Metric

Originally intended to demonstrate new processing effects added to Half Life 2: Episode 2 and future projects, the particle benchmark condenses what can be found throughout HL2:EP2 and combines it all into one small but deadly package. This test does not symbolize the performance scale for just Episode Two exclusively, but also for many other games and applications that utilize multi-core processing and particle effects. As you will see the benchmark does not score in FPS but rather in its own "Particle Performance Metric", which is useful for direct CPU comparisons.

IGP Gaming Benchmarks

IGP Gaming Benchmarks



In order to get an idea of how the new Intel HD Graphics 3000 integrated GPU performs we decided to compare it to the previous Intel GMA HD IGP (both 733Mhz & 900Mhz flavours) found in the Clarkdale chips, as well as AMD's latest IGP, the Radeon HD 4290 (40 unified shaders @ 700Mhz/UMA+SidePort DDR3-1333) found in the 890GX chipset. We also compared Intel's new IGP to a few low-priced discrete GPUs from AMD and NVIDIA.

Keep in mind that while both Sandy Bridge models in this review feature the higher-end Intel HD 3000 Graphics GPU with 12 EU's, the Core i5-2500K can only dynamically clock up to 1100Mhz, while the Corer i7-2600K can run all the way up to 1350Mhz.


Futuremark 3DMark06


3DMark06 v1.1.0

Things set off with a bang here as these new IGPs are able to thoroughly outstrip the previous generation in 3DMark 06 and even manage to run past the AMD HD 5450. Unfortunately, the lowest-end NVIDIA card we tried simply ran away with the show.


Futuremark 3DMark Vantage


3DMark Vantage v1.0.1
Graphic Settings: Entry Preset

Within a real-world gameplay scenario, things to change one bit as the new Intel IGPs continue to impress but they don’t really compare all that well against a sub-$100 dedicated GPU. It is just important to remember that Intel’s graphics controller isn’t compatible with the DX11 standard which is a shame considering we have seen several games perform better under DX11 than DX10 settings.

Power Consumption / Temperature Testing

Power Consumption


For this section, every energy saving feature was enabled in the respective BIOSes and the Windows Vista power plan was changed from High Performance to Balanced.

For our idle test, we let the system idle for 15 minutes and measured the peak wattage through our UPM EM100 power meter.

For our CPU load test, we ran Prime 95 In-place large FFTs on all available threads for 15 minutes, measuring the peak wattage via the UPM EM100 power meter.

For our overall system load test, we ran Prime 95 In-place large FFTs on all available threads for 15 minutes, while simultaneously loading the GPU with OCCT v3.1.0 GPU:OCCT stress test at 1680x1050@60Hz in full screen mode.

chart36.jpg

Considering the performance these two CPUs put forward, their power consumption numbers are really something to behold and they speak volumes about the maturity of Intel's 32nm manufacturing process. As a comparison, the new 2500K consumes about as much as the highly popular Core 2 Duo E8400; now that's progress!

Now onto the power consumption when using the IGP instead of a power hungry discrete GPU...

chart37.jpg

Power consumption numbers with the IGP enabled are interesting to say the least. It seems like the additional on-board graphics capabilities comes with a notable decrease in overall efficiency but considering the gap between the Clarkdale and Sandy Bridge graphics cores in performance, this was to be expected.


Temperature Testing



For the temperature testing, we used both the two stock Intel Sandy Bridge CPU coolers and a Thermalright Ultra-120 Extreme (TRUE). The ambient temperature was 24°C/75°F. The application used to monitor temperatures was HWMonitor 1.17.1.

Idle CPU + Idle IGP: The system was left to idle for 15 minutes.
Idle GPU + Load IGP: OCCT v3.1.0 GPU stress test was run at 1680x1050 for 15 minutes.
Load CPU + Idle IGP: Prime 95 In-place large FFTs was run for 15 minutes.
Load CPU + Load IGP: Prime 95 In-place large FFTs and OCCT v3.1.0 GPU stress test were run for 15 minutes.

chart38.jpg

With and without an aftermarket heatsink, the new Sandy Bridge processors are some cool-running products considering the clock speeds which they operate at. The reasoning behind the 2500K's higher reference temperatures boils down to the smaller, lower quality stock heatsink it comes with.

To see just how much (or little) the IGP contributed to the overall heat output we also measures temperatures while the IGP was idling and under full load. The below temps were achieved with Thermalright Ultra-120 Extreme in order to achieve normalized numbers.

chart39.jpg

Naturally, with the graphics core enabled the temperatures do tend to increase as more of the chip's transistors are being used. The increase however is anything but dramatic.
