Bioshock Infinite Results

Our Intel Skylake launch coverage is intense! Make sure you hit up all the stories and videos that are interesting for you!

Today marks the release of Intel's newest CPU architecture, code named Skylake. I already posted my full review of the Core i7-6700K processor so, if you are looking for CPU performance and specification details on that part, you should start there. What we are looking at in this story is the answer to a very simple, but also very important question:

Is it time for gamers using Sandy Bridge system to finally bite the bullet and upgrade?

I think you'll find that answer will depend on a few things, including your gaming resolution and aptitude for multi-GPU configuration, but even I was surprised by the differences I saw in testing.

Our testing scenario was quite simple. Compare the gaming performance of an Intel Core i7-6700K processor and Z170 motherboard running both a single GTX 980 and a pair of GTX 980s in SLI against an Intel Core i7-2600K and Z77 motherboard using the same GPUs. I installed both the latest NVIDIA GeForce drivers and the latest Intel system drivers for each platform.

  Skylake System Sandy Bridge System
Processor Intel Core i7-6700K Intel Core i7-2600K
Motherboard ASUS Z170-Deluxe Gigabyte Z68-UD3H B3
Memory 16GB DDR4-2133 8GB DDR3-1600
Graphics Card 1x GeForce GTX 980
2x GeForce GTX 980 (SLI)
1x GeForce GTX 980
2x GeForce GTX 980 (SLI)
OS Windows 8.1 Windows 8.1

Our testing methodology follows our Frame Rating system, which uses a capture-based system to measure frame times at the screen (rather than trusting the software's interpretation).

If you aren't familiar with it, you should probably do a little research into our testing methodology as it is quite different than others you may see online.  Rather than using FRAPS to measure frame rates or frame times, we are using an secondary PC to capture the output from the tested graphics card directly and then use post processing on the resulting video to determine frame rates, frame times, frame variance and much more.

This amount of data can be pretty confusing if you attempting to read it without proper background, but I strongly believe that the results we present paint a much more thorough picture of performance than other options.  So please, read up on the full discussion about our Frame Rating methods before moving forward!!

While there are literally dozens of file created for each “run” of benchmarks, there are several resulting graphs that FCAT produces, as well as several more that we are generating with additional code of our own.

If you need some more background on how we evaluate gaming performance on PCs, just check out my most recent GPU review for a full breakdown.

I only had time to test four different PC titles:

  • Bioshock Infinite
  • Grand Theft Auto V
  • GRID 2
  • Metro: Last Light

SLI and CrossFire

Last week I sat down with a set of three AMD Radeon R9 Fury X cards, our sampled review card as well as two retail cards purchased from Newegg, to see how the reports of the pump whine noise from the cards was shaping up. I'm not going to dive into that debate again here in this story as I think we have covered it pretty well thus far in that story as well as on our various podcasts, but rest assured we are continuing to look into the revisions of the Fury X to see if AMD and Cooler Master were actually able to fix the issue.

What we have to cover today is something very different, and likely much more interesting for a wider range of users. When you have three AMD Fury X cards in your hands, you of course have to do some multi-GPU testing with them. With our set I was able to run both 2-Way and 3-Way CrossFire with the new AMD flagship card and compare them directly to the comparable NVIDIA offering, the GeForce GTX 980 Ti.

There isn't much else I need to do to build up this story, is there? If you are curious how well the new AMD Fury X scales in CrossFire with two and even three GPUs, this is where you'll find your answers.

Just Arrived: MSI 990FXA-Gaming Motherboard

Tagged: msi, amd, 990fx, FX-8370, FX-9590, sli, crossfire, SoundBlaster, killer nic, usb 3.1

Several weeks ago MSI officially announced the 990FXA-Gaming motherboard for the AM3+ market.  The board is based on the tried and true 990FX and SB950 combo, but it adds a new wrinkle to the game: USB 3.1 support.  MSI has released the other AMD based USB 3.1 board on the market, the 970 Krait.

msi_990fxa_g_01.jpg

Quite a few people were excited about this part, as the AM3+ market has been pretty stagnant as of late.  This is not necessarily surprising considering that AMD has not launched a new AM3+ chip since Fall of 2014 with a couple of "efficiency" chips as well as the slightly faster FX-8370.

msi_990fxa_g_02.jpg

There was some speculation based on early photographs that the board could have a more robust power delivery system than previous AM3+ boards, but alas, that is not the case.  Upon closer inspection it appears as though MSI has gone the 6+2 phase route.  If there are good quality components in there, you can potentially run the 220 watt TDP FX-9000 series parts, but these puppies are not officially supported.  In fact, I received an email saying that I might want to be really careful in my choice of CPUs as well as being extremely careful when overclocking.

The board still has some real potential at being a really nice home for the 125 watt TDP and below parts.  The audio portion looks very well designed and features the SoundBlaster Cinema 2.  It supports both SLI and CrossFire in native 2 x 16x (highly doubtful with 3 cards with the way the slots are configured).  It has the Killer NIC ethernet suite which may or may not be a selling point, depending on who you ask.

msi_990fxa_g_03.jpg

Overall the board is an interesting addition to the club, but I really wouldn't trust it with the FX-9000 series chips.  I have a 970 Gaming that came with the FX-9590 that had a similar power delivery system, and it ran like a champ; there is a possibility that the board will run this combination.  This is going to be installed this weekend and I will start the benchmarking!  Keep tuned!

GTA performance part 2 ... GPUs

Subject: General Tech | May 6, 2015 - 03:46 PM |
Tagged: gaming, GTAV, 1440p, 4k, crossfire, sli

Last week [H]ard|OCP investigated the performance of GTAV on single GPU systems and this week comes the promised follow up featuring Crossfire and SLI, including the expensive Titan X.  With these high end setups, they tested 1440p and 4k performance as running these GPUs at 1080p is a crime against silicon.  At 1440p, the GTX 980 in SLI could handle more than a single Titan X though nowhere near what that card managed in SLI while on the AMD the 295X2 could keep up frame wise, but at the cost of some graphical extras.  At 4k resolutions, not even the mighty Titans could manage to run with all graphics options turned up, though it certainly did provide the best performance. AMD's GPUs lagged behind in performance however in scaling they were significantly better than NVIDIA's offerings, though there is still some room for improvement.  The real battle is at the $650 mark, you can choose between a pair of GTX 970's or a single R9 295X2 as they offer relatively similar performance but if you want the most out of GTAV you are going to have to pay much more than that.

You should also make sure to free up your calendar at the end of the month for the Fragging Frogs Virtual LAN Party #10 is coming up on the 30th!

First Glimpse of the MSI 990FXA-Gaming Motherboard

Some months ago MSI announced that they are releasing a slew of USB 3.1 compliant parts.  What was surprising was the mention of a brand new AM3+ board based on the now nearly geriatric AMD 990FX chipset.  The 990FX has had quite a lifespan with PCI-E 2.0 support and the accompanying SB950 southbridge with USB 2.0 and SATA6G features.

msi_990fxag.jpg

It looks as if MSI is doing a clean sheet design for the 990FXA-Gaming.  This looks to be a class leading product with plenty of features.  Not only does it have the USB 3.1 support, but it also implements the enhanced audio design that we have seen on other top end boards from MSI.  It also embraces the Killer ethernet software suite (utilizing Qualcomm's Atheros Gig-E chip).

The power delivery system looks to be a full 8+2 unit, so it can officially handle the 220 watt TDP FX-9000 series of CPUs.  It supports both SLI and CrossFire.  The cooling on the board looks to be top notch as well, with a heatpipe stretching from the Southbridge, through the Northbridge, and finally to the VRMs.

We expect these boards to be available sometime around the middle of this month.  We should also be receiving a sample for testing around then.  It is nice to see new support for AMD's FX CPUs, and this should be a cost effective member of the club.  Though AM3+ is a dead end in terms of socket infrastructure, there is still a lot of value in AMD's FX CPU line.

There is no word on pricing at this time, but I would not be surprised to see it hit the $149 mark.  It does not seem as decked out as the 990FXA-GD80 which is priced around $179.  With the robust featureset that they do implement, it does look to be a value if it can hit that aggressive price point.

Dual GPUs can still be quiet

Subject: Systems | March 13, 2015 - 06:12 PM |
Tagged: sli, quiet computing

Silent PC Review spends a lot of effort choosing components which offer a great performance but do not create a lot of noise and their latest sytem is a perfect example.  Even with a pair of air cooled GTX 970's and an i5-4690K this system only hit 23dBA under load, quiet enough for SPCR to confirm their 970's suffer from coil whine.  The sound came primarily from the GPUs as you would expect so it is possible that finding a very quiet radiator and watercooling them might reduce the sound produced even further.  It just goes to show how much quieter air cooling has become from the days of screaming 40mm Deltas.

Battlefield 4 Results

At the end of my first Frame Rating evaluation of the GTX 970 after the discovery of the memory architecture issue, I proposed the idea that SLI testing would need to be done to come to a more concrete conclusion on the entire debate. It seems that our readers and the community at large agreed with us in this instance, repeatedly asking for those results in the comments of the story. After spending the better part of a full day running and re-running SLI results on a pair of GeForce GTX 970 and GTX 980 cards, we have the answers you're looking for.

Today's story is going to be short on details and long on data, so if you want the full back story on what is going on why we are taking a specific look at the GTX 970 in this capacity, read here:

Okay, are we good now? Let's dive into the first set of results in Battlefield 4.

Battlefield 4 Results

Just as I did with the first GTX 970 performance testing article, I tested Battlefield 4 at 3840x2160 (4K) and utilized the game's ability to linearly scale resolution to help me increase GPU memory allocation. In the game settings you can change that scaling option by a percentage: I went from 110% to 150% in 10% increments, increasing the load on the GPU with each step.

bf4settings.jpg

Memory allocation between the two SLI configurations was similar, but not as perfectly aligned with each other as we saw with our single GPU testing.

bf4mem.png

In a couple of cases, at 120% and 130% scaling, the GTX 970 cards in SLI are actually each using more memory than the GTX 980 cards. That difference is only ~100MB but that delta was not present at all in the single GPU testing.

CES 2015: MSI GT80 Titan SLI 18-in Gaming Notebook with Cherry MX Brown Keyboard

Subject: Mobile, Shows and Expos | January 4, 2015 - 04:02 PM |
Tagged: titan, sli, msi, GTX 980M, gt80, cherry mx brown, ces 2015, CES

Back in late October MSI announced the GT80 Titan gaming laptop that included an impressive array of features, the most interesting of which was the full-size Cherry MX Brown keyboard embedded in the chassis. Seriously.

gt80-3.jpg

At CES this week we got hands on with the beast and I have to say I came away pretty impressed. Hardware powering the system includes an Intel Core i7-4980HQ processor, a pair of GTX 980M GPUs running in SLI, 24GB of DDR3 system memory, up to quad M.2 SSDs in RAID-0, Killer wired and wireless networking and more. All of that hardware sits under the top portion of the bottom of the notebook - the LED backlit Cherry MX Steel Series keyboard takes up the entire depth of the GT80 in the bottom portion.

gt80-2.jpg

Despite its appearance, the GT80 Titan is similar in size to some of the other 17/18-in Alienware notebooks currently selling, but they obviously don't include a Cherry keyboard will full travel switches. MSI also claims that access to the system memory, M.2 storage, 2.5-in HDD location and optical drive through the top panel allows for reasonable upgrade options down the road. Even the two MXM modules for the GTX 980M cards can be changed through the bottom of the GT80. (Mobile GPU upgrades have always been problematic.)

gt80-1.jpg

The GT80 Titan will be available next week and will start at $3299 with a $3499 option including the faster Intel processor. That is an incredibly high price for a gaming machine that is less "portable" than "transportable" but it would be hard to get more gaming horsepower in a smaller package anywhere else. We are looking forward to a review unit showing up shortly after our return! Stay tuned!
