Gaming Benchmarks: Low End

Alien: Isolation

If first person survival mixed with horror is your sort of thing, then Alien: Isolation, based off of the Alien franchise, should be an interesting title. Developed by The Creative Assembly and released in October 2014, Alien: Isolation has won numerous awards from Game Of The Year to several top 10s/25s and Best Horror titles, ratcheting up over a million sales by February 2015. Alien: Isolation uses a custom built engine which includes dynamic sound effects and should be fully multi-core enabled.

For low end graphics, we test at 720p with Ultra settings, whereas for mid and high range graphics we bump this up to 1080p, taking the average frame rate as our marker with a scripted version of the built-in benchmark.

Starting off with Alien Isolation really sets the pace for the rest of these iGPU benchmarks. So far in the socketed desktop AMD has been going up against Intel's Haswell Gen7.5 GT2 iGPU configurations, and trouncing them easily. However with the bump up in EUs that comes from going with GT3e, and a further bump from the Crystal Well eDRAM, Intel now has enough iGPU performance to push well past the AMD solutions and take the lead. Against the fastest socketed APU, the Kaveri Refresh A10-7870K, the Core i5-5675C has a 31% lead, and while we don't have the i7 available, it's reasonable to expect that it would be a bit faster, if only due to the 50MHz (5%) faster iGPU frrequency.

Otherwise looking at low-end dGPU performance, there's little to say. We're badly GPU-limited long before we get to the new Broadwell SKUs.

Total War: Attila

The Total War franchise moves on to Attila, another The Creative Assembly development, and is a stand-alone strategy title set in 395AD where the main story line lets the gamer take control of the leader of the Huns in order to conquer parts of the world. Graphically the game can render hundreds/thousands of units on screen at once, all with their individual actions and can put some of the big cards to task.

For low end graphics, we test at 720p with performance settings, recording the average frame rate. With mid and high range graphics, we test at 1080p with the quality setting. In both circumstances, unlimited video memory is enabled and the in-game scripted benchmark is used.

The i5-5675C's lead continues to be substantial here; Intel's i5 is ahead of the best AMD APU by 36%. Meanwhile we surprisingly see the Broadwell SKUs also edge out everything else to take the top spot in the low-end dGPU benchmark.

Grand Theft Auto V

The highly anticipated iteration of the Grand Theft Auto franchise finally hit the shelves on April 14th 2015, with both AMD and NVIDIA in tow to help optimize the title. GTA doesn’t provide graphical presets, but opens up the options to users and extends the boundaries by pushing even the hardest systems to the limit using Rockstar’s Advanced Game Engine. Whether the user is flying high in the mountains with long draw distances or dealing with assorted trash in the city, when cranked up to maximum it creates stunning visuals but hard work for both the CPU and the GPU.

For our test we have scripted a version of the in-game benchmark, relying only on the final part which combines a flight scene along with an in-city drive-by followed by a tanker explosion. For low end systems we test at 720p on the lowest settings, whereas mid and high end graphics play at 1080p with very high settings across the board. We record both the average frame rate and the percentage of frames under 60 FPS (16.6ms).

Though the i5-5675C and its Iris Pro 6200 GPU are still in the lead with Grand Theft Auto V, Intel's advantage has been curtailed significantly. to just 7%. Intel still has the lead, and it's large enough to matter, but it's still not very big compared to an AMD chip half its price.

GRID: Autosport

No graphics tests are complete without some input from Codemasters and the EGO engine, which means for this round of testing we point towards GRID: Autosport, the next iteration in the GRID and racing genre. As with our previous racing testing, each update to the engine aims to add in effects, reflections, detail and realism, with Codemasters making ‘authenticity’ a main focal point for this version.

GRID’s benchmark mode is very flexible, and as a result we created a test race using a shortened version of the Red Bull Ring with twelve cars doing two laps. The car is focus starts last and is quite fast, but usually finishes second or third. For low end graphics we test at 1080p medium settings, whereas mid and high end graphics get the full 1080p maximum. Both the average and minimum frame rates are recorded.

Intel's lead with GRID: Autosport is again not especially large, but it is a solid 10% advantage here.

Middle-Earth: Shadows of Mordor

The final title in our testing is another battle of system performance with the open world action-adventure title, Shadows of Mordor. Produced by Monolith using the LithTech Jupiter EX engine and numerous detail add-ons, SoM goes for detail and complexity to a large extent, despite having to be cut down from the original plans. The main story itself was written by the same writer as Red Dead Redemption, and it received Zero Punctuation’s Game of The Year in 2014.

For testing purposes, SoM gives a dynamic screen resolution setting, allowing us to render at high resolutions that are then scaled down to the monitor. As a result, we get several tests using the in-game benchmark. For low end graphics we examine at 720p with low settings, whereas mid and high end graphics get 1080p Ultra. The top graphics test is also redone at 3840x2160, also with Ultra settings, and we also test two cards at 4K where possible.

Finally, with Shadows of Mordor the Intel/AMD gap widens once more. The i5-5675C is 20% faster than the best AMD APU, and falls just short of cracking a 60fps average.

Conclusions on Low-End Graphics

The results of our look at iGPU gaming are clear: Broadwell-DT takes the iGPU performance crown from AMD's APUs. The advantage will vary with the game, but with an average lead of 20% and never once falling behind AMD's APUs, the i5-5675C and its Iris Pro 6200 are clearly the faster option. Ultimately nothing here should be a surprise to AMD - what's changed is not the existence of Iris Pro, but rather the fact that it now comes in a socketed form factor - but for system builders this represents a new option for building a system driven solely by its iGPU.

That said, with a price tag around 2x the cost of AMD's best APU, this is a very expensive way to get another 20%. Combining another CPU with a discrete GPU is almost certainly going to be a better option as far as cost effectiveness goes. But as far as integrated GPUs go Intel does hold the top position.

    And it's not THAT expensive. It's certainly not cheap, but it's reasonable considering Intel's dominance. Reply

    I would love to see a quad core clocked higher (or with better IPC). I don't use highly parallel software that much and I have no use for an integrated GPU.
    Sadly, with no competition, Intel has just been pumping the GPU for 4 generations in a row. Not that I blame them.

    Improving single threaded performance is extremely hard, just ask AMD. I'd expect improvements of 5-10% per generation for the next few years. Reply

    They could still raise the clock speed. Intel CPUs could hit 4GHz on air for years. Even the top-level Haswell can do it, but it's 4 core+HT part. If I could replace my i5-2500k with a 4GHz quad-core, that would be good enough for me. Removing the integrated GPU from the equation would yield even more thermal legroom for the CPU. But it's not happening. With CPU performance securely in their hands, Intel is trying to secure positions in GPU and mobile markets (they'd be crazy not to at least try to diversify).

    Yet raising the clock speed conflicts with higher IPC. Because raising clock speed needs a longer pipeline and a longer pipeline means taking a more serious hit for branch mispredictions. AMD has managed to seriously raise IPC with AthlonXP. Intel did it with their Core architecture. And nothing happened ever since. Because there's no more pressure on Intel and AMD doesn't have the cash to invest anymore.

    You don't know that the GPU is impeding clock rate.

    Increases to clock rate increase power consumption dramatically. You can always overclock Broadwell yourself.

    IPC has been steadily improving. Core 2, and anything from AMD, are far behind at this point.

    "IPC has been steadily improving. Core 2, and anything from AMD, are far behind at this point."

    Not really. If you look here: http://www.anandtech.com/show/7003/the-haswell-rev...
    You'll see there's usually less than 10% gained (watch the i7 3.5GHz parts). And that's spread over three generations. Broadwell bring another 2-3%.
    And yes, AMD has been playing the same game, only they're stuck in their Athlon64 days.

    Dude, Intel is offering exactly this with i7 4790K. A really highly clocked quad core. Use your external GPU and the iGPU won't consume any power nor limit clock speed. In fact it makes the die larger and thus helps cooling a bit. Reply

    Oh please. What a garbage excuse. "It's hard"? Intel's more than doubled IPC/Watt in their mobile chips over the last 3-4 years. They just don't care about high end IPC because they have no competition. Reply

    That is what the XEON offers a better price and value than the X58xx line if you don't need unlocked performance. You can buy many XEON 6 cores cheaper than the X58xx line. Reply

    I'm not so sure that high end desktop users are a large enough demographic that Intel will be complaining any time soon. Reply
