The MacBook Pro "Core i7" 2.3 15-Inch (Early 2011) technically is a "configure-to-order" configuration of the MacBook Pro "Core i7" 2.2 15-Inch (Early 2011), but also is documented as a separate model for reader convenience. Other than processor (and the corresponding larger level 3 cache), these two models are identical.
The MacBook Pro "Core i7" 2.3 15-Inch (Early 2011/Thunderbolt) features a 32 nm "Sandy Bridge" 2.3 GHz Intel "Core i7" processor (2820QM), with four independent processor "cores" on a single silicon chip, an 8 MB shared level 3 cache, 4 GB of 1333 MHz DDR3 SDRAM (PC3-10600) installed in pairs (two 2 GB modules), a 750 GB Serial ATA (5400 RPM) hard drive, an 8X DL "SuperDrive", dual graphics processors -- an AMD Radeon HD 6750M with 1 GB of dedicated GDDR5 memory and an Intel HD Graphics 3000 graphics processor that shares 384 MB of memory with the system -- and an integrated FaceTime HD webcam.
The standard configuration of this model has an LED-backlit 15.4" widescreen TFT active-matrix "glossy" display (1440x900 native resolution), but it also was available via custom configuration with a "high-resolution glossy" 1680x1050 display and a "high-resolution antiglare" 1680x1050 display for an additional US$100 and US$150, respectively.
Connectivity includes AirPort Extreme (802.11a/b/g/n), Bluetooth 2.1+EDR, Gigabit Ethernet, a Firewire "800" port, two USB 2.0 ports, separate audio in and out ports, an SDXC card slot, and a new "Thunderbolt" port that is backwards compatible with Mini DisplayPort and, likewise, supports an external display at 2560x1600 and passes an audio signal. Thunderbolt also supports other peripherals that use the Thunderbolt standard which provides up to 10 Gbps of bandwidth in both directions.
This model uses a "Unibody" aluminum case design -- milled from a single piece of aluminum -- and has a backlit keyboard, a "no button" glass "inertial" multi-touch trackpad, and a non-swappable battery design that provides an Apple estimated 7 hours of battery life.
Compared to its predecessor, this model has a very similar external enclosure, apart from a higher-resolution webcam and the aforementioned Thunderbolt port. Internally, however, it has a significantly faster architecture, faster RAM, and improved graphics.

||Core i7 (I7-2820QM)
||This model is powered by a "Quad-Core" 32 nm, 64-bit Intel Mobile Core i7 "Sandy Bridge" (I7-2820QM) processor which includes four independent processor "cores" on a single silicon chip. Each core has a dedicated 256k level 2 cache, shares 8 MB of level 3 cache, and has an integrated memory controller (dual channel).
This system also supports "Turbo Boost 2.0" -- which "automatically increases the speed of the active cores" up to 3.4 GHz to improve performance when needed -- and "Hyper Threading" -- which allows the system to recognize eight total "cores" or "threads" (four real and four virtual).

||Radeon HD 6750M*
||*This system has dual graphics processors -- an AMD Radeon HD 6750M graphics processor with 1 GB of dedicated GDDR5 SDRAM and Intel HD Graphics 3000 with 384 MB of DDR3 SDRAM shared with main memory. The system automatically switches between graphics systems based on use (when applications use OpenGL, Core Graphics or other graphically demanding technologies, the system will use the dedicated graphics card, otherwise it will use Intel HD Graphics to conserve battery life).
Also see: What type of video processor is provided by the "Unibody" MacBook Pro models? Is it upgradable? Which models have "dedicated" and "integrated" video memory?
||The AMD Radeon HD 6750M graphics processor has 1 GB of dedicated GDDR5 memory. On the other hand, the Intel HD Graphics 3000 graphics processor shares system memory. Apple reports that when using Intel HD Graphics, the "memory available to Mac OS X may vary depending on graphics needs. Minimum graphics memory usage is 384 MB". If the system is upgraded to 8 GB of RAM (or more), the amount of system memory used by the Intel HD Graphics 3000 is 512 MB.
||By default, this model has a 15.4" color widescreen LED-backlit TFT active-matrix "glossy" display with a 1440 by 900 native resolution. However, it also was available via custom configuration with a "high-resolution glossy" 1680x1050 display and a "high-resolution antiglare" 1680x1050 display for an additional US$100 and US$150, respectively.
In addition to the native resolution, Apple reports that this system also supports "1280 by 800, 1152 by 720, 1024 by 640, and 800 by 500 pixels at 16:10 aspect ratio; 1024 by 768, 800 by 600, and 640 by 480 pixels at 4:3 aspect ratio; 1024 by 768, 800 by 600, and 640 by 480 pixels at 4:3 aspect ratio stretched; 720 by 480 pixels at 3:2 aspect ratio; 720 by 480 pixels at 3:2 aspect ratio stretched."

It also supports the current version of OS X 10.10 "Yosemite" -- including Mac-to-Mac AirDrop and AirPlay Mirroring capability -- but other advanced features are not supported.
Please note that OS X "Lion" 10.7 and subsequent versions of OS X -- like Mountain Lion, Mavericks, and Yosemite -- are not capable of running Mac OS X apps originally written for the PowerPC processor as these operating systems do not support the "Rosetta" environment. To run PowerPC applications on this Mac, it will be necessary to use Mac OS X 10.6 "Snow Leopard."

||*Apple's Boot Camp 4 supports the 32-bit of Windows 7 on this model. Boot Camp 5 supports the 64-bit versions of Windows 7 and Windows 8. Earlier versions of Windows are not supported.
Although Apple does not support Windows 10 via Boot Camp 5 (officially or otherwise), this system meets Microsoft's hardware requirements and it very well may be possible to boot Windows 10 on this Mac. If you have installed Windows 10 on this system (successfully or unsuccessfully), please share the results of your experiment. Thank you.
