ZOTAC GAMING GeForce GTX 1650 – Best Small Graphics Card

View on Amazon

As a longtime fan of Zotac, I was extremely excited when they announced a new line of gaming graphics cards. And the fact that they are very compact is just icing on the cake.

So it is no surprise that my first review is a Zotac card.

This is the ZOTAC GAMING GeForce GTX 1650 OC 4GB GDDR6 128-bit Gaming Graphics Card, Super Compact, ZT-T16520F-10L. Let’s take a look at what this card has to offer.

The first thing you notice about this card is that it is a compact card. It only measures 5.94 inches in length and weighs in at a mere 1.2 pounds.

I have not seen a smaller GPU in a while, and I was impressed with how small it was. This makes it perfect for cases with less space.

If you have a micro-ATX case, you will not be able to fit this in. However, if you have an mITX case, this should fit perfectly. It will also fit into most standard mid-tower cases.

Another thing I like about this card is that it has a dual BIOS. You can have it set to either normal or OC mode.

The default setting is standard, so you will probably want to switch to OC mode. It is also capable of overclocking the card, which is a nice feature.

The GPU on this card is an NVIDIA GeForce GTX 1650 with an 8nm process. This GPU is slightly faster than the previous generation of cards, and it has more than enough power to handle any game.

This low power supply graphics card also has a TDP of only 150 watts. This is low power consumption, and you shouldn’t have to worry about it overheating.

Why Should You Go For It?

It is also easy to find replacement fans because the manufacturer includes the company’s name on the fan. This makes it easier to replace them.

Overall, this is a great compact card. It is mighty, and it is perfect for minor cases. If you’re looking for something small and powerful, this card is for you.

Base Clock1266 MHZ.
Boost Clock1367 MHz
CUDA Cores2048
Memory Detail4096MB GDDR5

The GeForce GTX 980 is simple to suggest to gamers looking to create a new rig for elevated gaming or upgrade an older card to achieve steady connection speeds at displays above 1080p, based solely on its efficiency and (comparatively) low power requirements.

The GeForce GTX 980 accelerates VXGI to the point that game designers can compute global illumination in-game, allowing vibrant colors to communicate with in-game objects (such as characters) real-time rather than being reflected onto static things like floors, walls, and furniture.

Compared to the GeForce GTX 680, it has doubled the number of render output units (ROPs). This, coupled with a higher clock speed (on the stock GTX 980, approximately 1,126MHz and 1,216MHz), is intended to improve performance at high resolutions and when high anti-aliasing settings are available.

The AMD card is still high-speed, but it’s expected to draw between 270 and 300 watts at load, based on power-connector specifications.

A new anti-aliasing method, a new dynamic lighting effect, and Dynamic Super Resolution are among the features supported by the GeForce GTX 980.

Attempts to provide better image quality on lower-resolution displays by rendering at higher resolutions and downsampling the results.

The GeForce GTX 980 features 4GB of GDDR5 RAM that runs at an effective 7Gbps and a lead-up engine that Nvidia claims cuts memory bandwidth demands.

Nvidia is boasting a few additional in-game functionalities with the GeForce GTX 980, in addition to a new architecture that stresses efficiency and support for the upcoming DirectX 12 API (of course).

On a Dell 1080p computer, we briefly tested out Dynamic Super Resolution for a couple of our test games during our training.

I was enabling the Nvidia Control Panel option results in higher “virtual resolutions” appearing in the game’s configuration dialogues.

The GTX 980 model card has three DisplayPort ports, which addresses one of the issues with previous-generation Nvidia high-end cards.

You can attach three of these monitors to a single GeForce GTX 980 card). The HDMI port on this device is also of the brand-new 2.0 type, allowing it to support 4K resolution at 60Hz.

It runs cooler and quieter than comparable AMD cards and requires much less power than similar AMD cards.

The reversible hatch is designed to increase ventilation and cooling systems with several GeForce GTX 980 cards nearby.

According to Nvidia, the extra airflow provided by eliminating this portion of the backplate is critical for feeding air to the adjacent card’s intake fan.

Why Should You Go For It?

Nvidia’s high-end Maxwell-based card offers the highest single-chip gaming graphics card output to date by using far less power than the competition. 300 watt psu price is comparable with AMD’s more powerful Radeon R9 290X.

Asus GeForce GTX 1050 Ti

View on Amazon
CUDA Cores768
Graphics Clock1290 (MHz)
Processor Clock(MHz) 1392
Graphics PerformanceHigh-6747

Nvidia expands its 10-series GPU range with six new models with the introduction of the GTX 1050. If you can deal with the 2GB VRAM restriction, the GTX 1050 promises to be the highest overall budget GPU.

The GTX 1050 is the best ultra-low-cost GPU. It’s adequate for entry-level gaming and light esports, and it should fit in almost every machine sold in the last five years or more.

The same GP107 GPU is used on both cards based on Samsung’s 14nm FinFET node. Furthermore, 1050 comes with 2GB GDDR5 memory (depending on the games and settings you choose).

But there’s more to it than that. With just 640 CUDA cores, this is the most basic Pascal chip available. This model’s lack of cores is compensated for by a high boost clock speed of 1,455MHz.

Pascal has a lot of quality, and it has some incredible results in the end. In the end, the GTX 1050 outperforms the GTX 950. Anyone who sees the GTX 1050 and thinks to themselves, “Yeah, that’s just the kind of results I need.”

All you need is a full-size slot with an x16 PCIe link to install a 1050 and get a significant performance boost over integrated graphics.

This recommended psu 300w is also a decent HTPC solution, as the card retains all of the HEVC decoding capabilities of the more costly Pascal offerings.

They provide superior raw value to the AMD graphics cards used in the base PlayStation 4 and Xbox One versions. However, most gamers would be best suited by a higher-end card with 3GB or more VRAM due to the card’s local video memory.

A tiny heatsink and a single fan keep it cold, and it’s housed in EVGA’s fashionable but straightforward black and grey plastic shroud.

The real kicker is the power use. The GTX 1050’s TDP (thermal design efficiency) is only 75W, which means it gets all of its power from your motherboard.

During the Hitman benchmark, the whole machine on our high-end, overclocked PC drew just 150W, 61W more petite than the RX 460.

Why Should You Go For It?

The GTX 1050 is the best demonstration yet of Nvidia’s Pascal architecture in use.

It may not achieve stellar benchmark performance, but as a replacement part for an outdated or disabled GPU, it’s excellent, and it should not necessitate upgrading the power supply. It is the highest low-cost GPU for eSports players.

  • Excellent price
  • HDMI 2.0b, DisplayPort 1.4
  • Handles all games at Full HD

EVGA GeForce GTX 750Ti

View on Amazon
Cores640 CUDA
Base Clock1020 MHz
Boost Clock1085 MHz
Memory Clock5.4 Gbps

The 750 Ti is the green team’s newest addition to the industry, providing gamers with a low-cost 1080p gaming video card.

The 750 Ti outperformed the AMD cards in every benchmark, making it the absolute winner in raw results. Although the 260X is a rebadged Radeon HD 7790, the 750 Ti is based on Nvidia’s latest Maxwell GPU architecture. 

Nvidia’s 750 Ti is 22 percent better than the 600 series card when both metrics are combined. The 750 Ti supports G-Sync, a new Nvidia technology that allows GeForce video cards to play games without stuttering or screen tearing caused by high refresh rates.

The fact that the 750 Ti does not need any extra power connections is much more remarkable.

The 750 Ti has one Mini-HDMI port and two Dual-Link DVI ports, which can accommodate three screens. The 750 Ti is a low-power video card that uses only 60 watts.

With its 115W TDP, AMD’s R7 260X consumes nearly twice as much power. The 750 Ti’s power supply-demand is also minimal, at just 300W, so you will not need a big 500W or 750W beast to control it.

Because of this, and because of its limited scale, it’s a simple improvement for an extensive range of systems.

The card has 512 CUDA cores, a 1020MHz base clock, and a 1085MHz boost clock. The 750 Ti also has 2GB of GDDR5 video RAM running at 5400MHz.

If you are going to use different monitors, this 2GB Ti version is the way to go, so you will have more video RAM space to work with.

Using EVGA’s Precision X overclocking tool, I overclocked the 750 Ti by increasing its boost clock to 1169MHz.

There were no noticeable reliability problems, and overall performance increased by around 5% for all titles, except Batman: Arkham Origins, which only saw a 3% performance improvement. 

The 300w power supply graphics card is just 5.7″ (14.5cm) in length and has just one slot. The noise and cooling were not an issue, and it wasn’t significantly quieter than when it was stock clocked. With the Steam Box revolution just around the corner, that’s a wise design decision.

Why Should You Go For It?

With the 750 Ti, Nvidia has brought it to AMD, uses less fuel, and outshines both the R7 260X and the HD 7790 in competitive and digital comparisons by a margin of 11%.


  • Excellent power consumption
  • Cool and very quiet


  • No SLI support

Memory Clock1750 MHz
Memory Speed7 Gbps effective
Boost FrequencyUp to 1200 MHz

Sapphire has been a well-known brand producing graphics cards for over ten years. 

The Radeon RX 460 is their latest graphics card, so I decided to look at this one. 

The Radeon RX 460 is a mid-range graphics card that performs well enough to handle the majority of popular titles, with some exceptions.

This 300w psu graphics card has two HDMI outputs and a DVI-D port, too, so you can connect it to your monitor. 

It’s also equipped with dual 8-pin power connectors so that you will not be having any problems powering it up. It’s also a PCI-E 2.0 card so you won’t have any compatibility issues. 

Sapphire claims that the Radeon RX 460 is 25% more power-efficient than a standard choke, and it can run at lower temperatures too.

The company claims that the card only generates 65W of heat, less than half of what most other graphics cards produce. 

The Radeon RX 460 is fully unlocked so that you can overclock it to the highest settings. Sapphire says that this card will perform well on high-end machines, and it should be compatible with most motherboards out there. 

Why Should You Go For It?

This is the best choice for people who want to spend less money but still want to play the latest games. 

It’s also pretty cheap and has a great warranty. If you are looking for a good value for the money graphics card, get the Sapphire Radeon RX 460.


  • Fast enough for 1080p in many games
  • Affordable
  • Power Friendly


  • Performance has limits, even at 1080p
  • On par with the year-old GTX 950 in terms of performance

Its low-profile design allows it to fit into a standard PCI Express x16 slot, and it has integrated dual BIOS and dual SLI connectors. This makes it compatible with most motherboards and slots. 

With a power requirement of 300 watts, you won’t need to worry about replacing power supplies.

This graphics card should run well on low-power setups, but it also comes with a 6-pin PEG connector to power a dedicated power supply. 

The included heatsink keeps the temperature of the GPU at around 50 degrees Celsius, so you won’t have to worry about overclocking. 

It also has a fan, which keeps the temperature of the GPU at around 30 degrees Celsius. If you’re looking for a low-profile graphics card that will do well in low-power setups, this is for you. 

I was able to test it in two different configurations, and it performed very well in both.
