High Performance, Low Energy Consumption

pny-geforce-gtx-750-gtx-750-ti-gtx-750-ti-oc-custom-pc-review-16Recently, we came away very impressed with the MSI GeForce GTX 750 Gaming GPU, which was our first opportunity to check out a graphics card based off of Nvidia’s new Maxwell based GeForce GTX 750 series GPU. The GTX 750 series GPUs are Nvidia’s first GPUs to use Nvidia’s brand new, highly efficient SMM architecture to replace the older SMX architecture used on Nvidia’s previous generation Kepler based GPUs.

At launch, we unfortunately only got the opportunity to check out the GTX 750, which was the entry level GTX 750 series GPU. Alongside the GTX 750, Nvidia also launched the GTX 750 Ti, which is very similar to the GTX 750 with the exception that it had an extra SMM unit unlocked giving it access to 640 CUDA cores and 40 TU (Texture Units). The GTX 750 Ti also includes an additional 1GB of higher clocked GDDR5 which should theoretically give it a boost when gaming at higher resolutions.

Since we never had a chance to check out the GTX 750 Ti, we were thrilled when PNY offered us an opportunity to review their complete GeForce GTX 750 series lineup which includes the PNY GeForce GTX 750, GTX 750 Ti and the GTX 750 Ti OC. The PNY GeForce GTX 750 and the GTX 750 Ti are pretty much reference spec so reference PCB and reference clock/memory speeds, while the GTX 750 Ti OC edition will come aggressively pre-overclocked out of the box.

Let’s take a closer look at PNY’s GeForce GTX 750 series offerings.

A Closer Look at the PNY GeForce GTX 750, 750 Ti, 750 Ti OC

pny-geforce-gtx-750-gtx-750-ti-gtx-750-ti-oc-custom-pc-review-8

Here’s a look at the PNY GeForce GTX 750, GTX 750 Ti, and GTX 750 Ti OC. The packaging between the three graphics cards are pretty much identical with the exception of different labels for the different cards.

pny-geforce-gtx-750-gtx-750-ti-gtx-750-ti-oc-custom-pc-review-7

Accessories between the three cards are identical. Each card gets some documentation, a driver disk, DVI to VGA adapter, and a mini-HDMI to HDMI adapter.

PNY’s design for the GeForce GTX 750, GTX 750 Ti and GTX 750 Ti OC are pretty much the same, very similar to the reference design with a PNY branded cooler.

pny-geforce-gtx-750-gtx-750-ti-gtx-750-ti-oc-custom-pc-review-15

Unlike the previously reviewed MSI GeForce GTX 750 Gaming with its excessively monstrous cooler, the PNY GeForce GTX 750/750 Ti/750 Ti OC cards are appropriately sized, measuring in at just under 7″ in length. These cards should easily fit into any case with room for a double slot card.

Removing the cooler, we can take a closer look at the cooler assembly, PCB design and components used onboard.

The cooler is a custom PNY cooler that’s a fairly basic which includes a heatsink assembly and a fan. The cooler also includes a shroud to redirect heat out the back of the card.

Comparing the components on the PNY GeForce GTX 750, GTX 750 Ti and GTX 750 Ti OC, everything is almost the same with the exception of the GPU and the memory. Whereas the GTX 750 uses the GTX 750 GPU paired with 1GB of SK Hynix GDDR5, the GTX 750 Ti and GTX 750 Ti OC uses the GTX 750 Ti GPU paired with 2GB of Samsung GDDR5.

Crysis 2

As the successor to Crysis, which was hailed as the most graphically intensive game of all time when it was released in late 2007, Crysis 2 is less graphically demanding than its predecessor, but still one of the most graphically challenging games of all time.  You simply can’t take a step in Crysis 2 without stepping into some intense tessellation. Combined with rich lighting, insane physics, and oodles of post processing, Crysis 2 requires a ton of graphics muscle to run.

Today, we’ll be benchmarking Crysis 2 in the map “Central Park” with the Adrenaline Crysis 2 Benchmark Tool.

Battlefield 4

bf4 2013-11-19 01-48-20-20

Only a year after the initial release of Battlefield 3, the team at DICE went back to the drawing board to introduce their latest and greatest modern combat shooter, Battlefield 4. Based off DICE’s all-new Frostbite 3 engine, Battlefield 4 brings a new level of realism to the world of PC and console gaming with an unparalleled level of visual immersion, realistic character animations, and physics driven dynamic environments.

For our benchmarking, we’ll be doing a benchmark on a 60 second run of the game at the beginning of the Tashgar mission. While this scene doesn’t involve any firefights, it’s a very graphics intensive scene that involves a fast moving drive through the hills of Tashgar, which makes heavy use of the Frostbite 3’s motion blurring, depth of field, particle effects, and real time lighting engine.

PNY GeForce GTX 750, 750 Ti, 750 Ti OC Performance

Power Consumption

For power consumption testing, we’ll be measuring full system power while idle along with full system power with the graphics card running at full load using Furmark. All power consumption measurements will be measured with the Extech 380801 Power Analyzer.

power-consumption-pny-geforce-gtx-750-gtx-750-ti-gtx-750-ti-oc-custom-pc-review

Temperature Testing

For temperature testing, we’ll be measuring both graphics card temperatures when the graphics card is idle for 5 minutes after a cold boot. Load temperatures are taken after a full 30 minute burn using Furmark.

While some of you aren’t huge fans of Furmark as it creates an ultra heavy, unrealistic load on the graphics card, we feel like it’s a more useful tool as it differentiates between graphics cards that have extremely well designed coolers and ones that simply have cooling solutions that simply pass the test, if you will. Most games these days generally don’t create enough of a load/heat to even exceed temperatures where the fans would spin up on most custom coolers so it’s difficult to adequately rank cooling solutions without using a tool like Furmark.

PNY GeForce GTX 750, 750 Ti, 750 Ti OC Overclocking

As PNY doesn’t include any additional overclocking software, we used MSI’s Afterburner utility to overclock the graphics cards reviewed today.

PNY GeForce GTX 750

oc-gpuz-pny-geforce-gtx-750-custom-pc-review

The PNY GeForce GTX 750 is capable of the largest memory overclocking gains of any of the PNY GeForce GTX 750 series GPUs, achieving a maximum overclock of 1298MHz core and 1603MHz memory (6.4GHz effective) from stock clocks of 1085MHz core and 1253MHz memory (5GHz effective). The SK Hynix GDDR5 is definitely a stronger overclocker than the Samsung GDDR5 used on the GTX 750 Ti.

PNY GeForce GTX 750 Ti

oc-gpuz-pny-geforce-gtx-750-ti-custom-pc-review

The PNY GeForce GTX 750 Ti overclocked significantly without issue as well, achieving a maximum stable overclock of 1298MHz core and 1550MHz memory (6.2GHz effective) from stock clocks of 1085MHz core and 1350MHz memory (5.4GHz effective).

PNY GeForce GTX 750 Ti OC

oc-gpuz-pny-geforce-gtx-750-ti-oc-custom-pc-review

Since PNY already overclocks their GeForce GTX 750 Ti OC by quite a bit, we weren’t able to squeeze too much more out of the card, but we were able to achieve a respectable 1398MHz core and 1552MHz memory (6.2GHz effective) from the stock 1281MHz core and 1502MHz memory (6GHz effective).

3D Mark Performance – Fire Strike

oc-3d-mark-firestrike-pny-geforce-gtx-750-gtx-750-ti-gtx-750-ti-oc-custom-pc-review

With our huge overclocks on the GTX 750 and GTX 750 Ti, we were able to get ~12% increase in performance in the 3D Mark Fire Strike benchmark. With the already overclocked GTX 750 Ti OC, additional overclocking gains were far less with only a 1% increase in performance.

Power Consumption

oc-power-consumption-pny-geforce-gtx-750-gtx-750-ti-gtx-750-ti-oc-custom-pc-review

The Maxwell architecture that the GTX 750 series is built on is incredibly efficient with the entire lineup of cards tested today coming in at 144w or under at load. Interestingly enough, the GTX 750 Ti OC card drew less power at load at stock, which could indicate that the specific GTX 750 Ti GPUs used on the OC units are more efficient than the non-OC units. Of course, this is not at all definitive as we only have a sample size of one.

Temperatures

oc-temperatures-pny-geforce-gtx-750-gtx-750-ti-gtx-750-ti-oc-custom-pc-review

Because of Maxwell’s efficiency, the entire GTX 750 series lineup runs incredibly cool, never breaking 59°C under load. Interestingly, the GTX 750 seems to run a bit warmer than the GTX 750 Ti and the GTX 750 Ti OC chips, but even 59°C is well within the safe zone.

PNY GeForce GTX 750, 750 Ti, 750 Ti OC Scrypt Mining (Bitcoin, Litecoin, Dogecoin, etc)

Like it or not, GPU mining for cryptocurrencies is all the rage these days so we’ll also be doing a bit of scrypt mining testing as well. For our testing today, we’ll be using cudaMiner which is a great scrypt mining application designed for Nvidia GPUs.

Performance Analysis

Given Maxwell’s architectural efficiency, the GTX 750 series GPUs are probably Nvidia’s most efficient scrypt mining GPUs. With each GPU overclocked, the GTX 750 was able to achieve 222 khash/s, the GTX 750 Ti was able to achieve 270 khash/s and the GTX 750 Ti was able to achieve 291 khash/s.

PNY GeForce GTX 750, 750 Ti, 750 Ti OC Conclusions

pny-geforce-gtx-750-gtx-750-ti-gtx-750-ti-oc-custom-pc-review-1PNY isn’t really known for producing the craziest custom coolers or packing in the most overclocking friendly features into their graphics cards, but I think with something like the GTX  750 and the 750 Ti, they’re right on the mark. After previously having the opportunity to check out the MSI GeForce GTX 750 Gaming with its unnecessarily large PCB and massive cooling solution, I think PNY’s implementation is the better option as the smaller size of the card is a lot more versatile for the many users planning to install the graphics cards into smaller form factor PCs or pre-built PCs that don’t necessarily have external PCIe connectors and are severely limited in space.

Performance-wise, we’ve definitely come away impressed with all the graphics cards tested today. Despite all the cards being limited by the PCIe slot’s 75w power envelope, the GTX 750 and the GTX 750 Ti is capable of playing most of the latest games at medium/high settings at 1920×1200 – something we’ve only dreamed about a couple years ago. Obviously those wanting to turn up the settings a bit, or are more interested in playing more graphically demanding games should go with the GTX 750 Ti whereas those who simply want to be able to run games at 1080p with medium quality settings can go with the GTX 750.

As for overclocking performance, there’s definitely a lot of room here with both the PNY GeForce GTX 750 and GTX 750 Ti. With a bit of tweaking, we were easily able to squeeze around a good 12% increase in performance in both the GTX 750 and the GTX 750 Ti. The PNY GeForce GTX 750 Ti OC on the other hand doesn’t have too much overclocking headroom given the fact that PNY has already aggressively overclocked the card by about 18% core and 11% memory. While this may be disappointing for some users, I think it actually gives a lot of value to those who aren’t comfortable overclocking their graphics cards as PNY’s GTX 750 Ti OC card is really pushed to the limits rather than a 2% higher clocked card with an additional $10 bump in the price by it being “overclocked”.

Currently, street prices on the PNY GeForce GTX 750, GTX 750 Ti and GTX 750 Ti OC are $124.99, $149.99, and $159.99 respectively, which is pretty much MSRP for GTX 750 series graphics cards. While PNY’s GTX 750 series graphics cards don’t necessarily include amazing custom features and board designs, they do offer a limited lifetime warranty with their cards with registration, which is not always something you’d find from most GPU vendors. PNY’s background with most of their product lines has always been reliability rather than extreme overclocking as much of their business is in the OEM and professional markets.

Overall, the PNY GeForce GTX 750, GTX 750 Ti and GTX 750 Ti OC are fantastic reference based designs that fit very well into the market segments that they cover. Those with older systems that don’t have access to external PCIe power, or those looking to fit a graphics card into a smaller form factor system should definitely keep an eye out for PNY’s selection of GTX 750 series based graphics cards.

    Beware, many reviews from customers having bad experience with PNY warranty. Apparently “lifetime” is a lie, a play on words. For example, if they stop producing that card, their warranty is null and void, they expect you to pay shipping both ways and other catches. You could buy a video card with a “lifetime warranty” one day, then have that “life time” be over the literal next day because they no longer make that specific card.

    Also read that their customer support sucks badly, hard to talk to, and may just ignore you.
