Crysis Benchmark Results

Crysis uses a new graphics engine: the CryENGINE2, which is the successor to Far Cry's CryENGINE. CryENGINE2 is among the first engines to use the Direct3D 10 (DirectX 10) framework, but can also run using DirectX 9, on Vista, Windows XP and the new Windows 7. As we'll see, there are significant frame rate reductions when running Crysis in DX10. It's not an operating system issue, DX9 works fine in WIN7, but DX10 knocks the frame rates in half.

Roy Taylor, Vice President of Content Relations at NVIDIA, has spoken on the subject of the engine's complexity, stating that Crysis has over a million lines of code, 1GB of texture data, and 85,000 shaders. To get the most out of modern multicore processor architectures, CPU intensive subsystems of CryENGINE 2 such as physics, networking and sound, have been re-written to support multi-threading.

Crysis offers an in-game benchmark tool, which is similar to World in Conflict. This short test does place some high amounts of stress on a graphics card, since there are so many landscape features rendered. For benchmarking purposes, Crysis can mean trouble as it places a high demand on both GPU and CPU resources. Benchmark Reviews uses the Crysis Benchmark Tool by Mad Boris to test frame rates in batches, which allows the results of many tests to be averaged.

Once again, we are going to concentrate on relatively low-resolution testing performance. At the 1280x1024 resolution used by 17"; and 19"; monitors, the CPU and memory may have some influence on the results, but our test rig in this case is well above the specs that a typical HD5450 user will have, so we've eliminated that variable. At 1280x1024, and the widescreen resolutions of 1680x1050, the performance differences between the video cards under test are mostly down to the cards.

The results here are pretty consistent with 3DMark Vantage, in that the HD5450 is stuck in a range close to, but below the teens. For most users, the performance of the HD5450 in this challenging scenario is going to be frustrating, ultimately unacceptable, and bordering on painful. Comparing the HD5450 directly against its higher priced siblings shows that performance goes up almost exponentially. The HD5670 costs twice as much, but has almost ten times the performance in this real-world application. Anyone looking to play a little Crysis on their 1080P HTPC needs to look at either the HD5670 or perhaps the soon-to-be-released HD5570 as a minimum starting point.

Once a decent amount of anti-aliasing is factored in, the situation degrades even further. Frame rates are way below acceptable until you get close to the $100 mark with the HD5670. If you want to play this game in DX10 with eye candy turned on, you are going to have to pay, both with cash as well as increased heat and power consumption.

is ATI Radeon HD5450 compitable with intel dual core 2.8 Ghz processor ?
Please reply as early as possible

Yes. All video cards are compatible with all processors. Just make sure the motherboard has a PCI-Express graphics slot.

how to make sure the mother board has a pci-slot?

Wikipedia has some good pictures on the PCI Express page that show what they look like

Is is good foor games?Will it play them fast? I don't know so much about hardware and stuff...

# Not so muchBruce 2012-04-24 07:50
This card is on the low end of discrete graphics.
It's really better suited to a Home Theater PC.

# Fan connectorRoger 2012-06-01 17:01
I see there is what looks like a fan connector on the card - is this correct and if so what would be the power specs for a fan?

If you look at some of the other HD 5450 cards out on the market (Newegg has 34 models for sale, 2+ years after launch...!) you wll see that many of them have active cooling, with a fan plugged into this very same header. It's only two pins, so don't expect PWM or anything, just straight DC with no speed monitoring.

The PCI slot has to have the little gap thing, the oppisite way around that does the graphics card have so for instance -- ---- and ---- -- and most of all if the the ports on the graphics card are pointing toward the outside, etc.

# Re Fan ConnectorRoger 2012-06-02 18:10
Thanks for that Bruce,

Just to clarify such a connected fan would be of similar size and watts etc. to an inbuilt one?

Like I have a spare fan DC 12v 0.11A which is probably ok and another which is DC 12v 0.70A which is probably too powerful?

# Yes, again....Bruce 2012-06-03 06:58
That's the idea. It's not going to be an exact science, but most fans that are small enough and thin enough to fit on that card's heatsink will be fine. I've been assuming that you want to cool the GPU on the HD 5450 with this fan... right?

# Thats right Bruce...Roger 2012-06-03 22:01
I figure one cannot have enough fans (especially where I live in the tropics) so I might as well use a spare fan to play on the heatsink. The card will be on the bottom of the mobo with the heat sink facing down so I will mount the fan on the case bottom facing up to the heatsink.

Thanks again

I badly needed an htpc graphic card for my htpc. I am really having a hard time choosing because i really don't have any idea with these kind of things. But anyways, you're post is quite helpful. Thanks!

# No, It's NotBruce 2013-03-08 14:02
It is not good for high resolution games.
It was designed for HTPC use, which is much less demanding.
Plus, it was released three years ago, that's a LONG time in video card history. Why are you interested in it now? Can you even buy one in your location?
