The Fire HD, also known as Kindle Fire HD prior to 2014, is a member of the Amazon Fire family of tablet computers. Fire HD refers to Amazon Fire family tablets with HD resolution displays.^[3] These devices run the Fire OS operating system.

The first Fire HD model was announced on September 6, 2012, and was available in two versions: 7" and 8.9". The 7" model was released in the United States on September 14, France, Germany, Italy, Spain and the United Kingdom on October 25 and in Japan on December 18. The 8.9" model was released on November 20 in the United States, in Japan on March 12, 2013, in Germany on March 13, and in India on June 27.^{[4][5][6][7][8][9]}

On September 25, 2013, an updated Fire HD 7 was quietly announced alongside the newly debuted flagship Kindle Fire HDX line.^[10] It was available as a pre-order until the official ship date of October 2, 2013. Changes include: price reduction to $139, processor speed upgraded to 1.5 GHz, firmware upgrade from the unnamed "Android based" OS to a compatible proprietary fork of Android named Fire OS 3, removal of the front camera, new shell form factor, and decreased available storage options.

On October 2, 2014, the next revision of Fire HD models were released, part of the Fire Tablet's fourth generation, with 6-inch and 7-inch touchscreen sizes. In addition, the Fire HD Kids Edition was released, which is the same device as the Fire HD 6 except it comes with a case and one-year subscription to Kindle Freetime apps.^[11] The branding "Kindle" was officially removed from the tablets' name.^[12]

In September 2015, Amazon released a new range of Fire tablets with 7-, 8-, and 10.1-inch sizes. The 7-inch was simply called the Fire 7, while the 8-inch and 10.1-inch were called Fire HD 8 and Fire HD 10 respectively. Amazon had ended the HDX line after two generations and the new model range shifted the entire Fire tablet line down-market, with Fire 7 as the lowest priced Fire tablet at $50.

All 4th and 5th generation Fire HD models use the same quad-core MediaTek System-on-a-Chip (SoC) with 1 GB of RAM.

In September 2016, Amazon announced the release of the updated Fire HD 8 which includes the virtual assistant Alexa,^[13] priced at US$89.99. Fortune reported that, "As with most of Amazon's devices, the aim isn't to make money off of the hardware but instead to sell digital content such as books, movies, and TV shows to users".^[14] The new model also included a faster SoC and 1.5 GB of RAM.

On June 17, 2017, the seventh Generation Fire HD 8 was released. Some differences between the 6th and 7th Generation HD 8 models were the price, the gyroscope removal, the increase of maximum SD card expansion, and the better graphics chip.

On October 11, 2017 the 7th gen Fire HD 10 was released. It included a full HD 1920 by 1200 pixel display and a faster SoC and 2 GB of RAM.

In September 2018, Amazon released a refresh of the Fire HD 8/Kids Edition. The price remained the same as last year's model with minor upgrade on the hardware where the external storage is expandable to 400 GB and the front camera was updated to 2 MP. On the software side, the 2018 model is preinstalled with Fire OS 6 that allows hands-free Alexa control.

On October 7, 2019, Amazon announced an update to the Fire HD 10 that was released on October 30, 2019. The major hardware differences compared to the previous version were replacement of microUSB with USB-C, a faster processor (upgraded from Quad-Core up to 1.8 GHz to Octa-core 2.0 GHz, which Amazon claims is 30% faster than the previous one) and battery life that is 2 hours longer than the previous generation. The screen size and price remained unchanged. A new color option, white, was also added.

In 2020, the Fire HD 8 was updated with a faster 64-bit quad-core SoC, more storage (from 16/32 GB to 32/64 GB), USB-C, brighter display, enhanced wifi fidelity, a new front camera location (for landscape video chats instead of portrait), and Fire OS 7 (based on Android 9). It came in two versions: 2 GB RAM (HD 8) and 3 GB RAM (HD 8 Plus). The 3 GB RAM version, which enabled more memory-intensive apps, was available only in US, UK, DE, and JP marketplaces.

In 2021, the Fire HD 10 was refreshed with a new front camera location (for landscape video chats instead of portrait) and slimmer side bezels, leading to a more symmetrical design. Also, wireless charging was introduced for the "HD 10 Plus" model. The HD 10 Plus also has 4 GB of RAM.

On September 20, 2022, Amazon announced an update to the HD 8 as a 12th generation model.^[15] The new model is the first to run the new Fire OS 8. It also has a faster SoC and improved battery life.

In 2023, Amazon released an all new size of Fire tablet called Fire Max 11. The device features a larger display at 11" with official USI2.0 stylus support, pogo pins for an external keyboard, and a fingerprint sensor. All Max 11 have a partially recycled aluminum rear housing instead of plastic.^[16] All are new technologies to Fire tablets. A short-lived option for an aluminum rear-housing was available for the 5th gen HD 10 and was not continued on later gens.^[17] It also features newer hardware such as a faster and more efficient octa-core SoC, 4 GB RAM, 8 MP cameras, WiFi 6, and Bluetooth 5.3 BLE. Despite the change of naming convention Amazon considers the Max 11 to be in the Fire HD series.^[18]

On September 20, 2023, Amazon held a Device & Services event where they announced two new Kids models, the HD 10 Kids and HD 10 Kids Pro.^[19] Both have an MSRP of $189.99. Older models based on the 2021 HD 10 were discounted to a sale price of $139.99 from $199.99.^[20] The product descriptions show the new models as variants of the otherwise unannounced 2023 release for the 13th gen Fire HD 10.^[21] Shortly after the event official Amazon store pages and documentation showed a new 2023 model of the HD 10 with the model number KFTUWI.^[22] It has new hardware features from the Max 11 such as active stylus and detachable keyboard support. The product page for the device listed it as a pre-order for $139.99 and to be available on October 18, 2023.^[23]

On October 2, 2024, the Fire HD 8 was refreshed with more RAM.^[24] The 2024 model is still part of the 12th generation of Fire tablets and the hardware specs are nearly identical to the 2022 Fire HD 8 Plus model. Amazon did not release a Plus model in the 2024 refresh, and the 2024 HD 8 does not gain the wireless charging feature. Instead, the HD 8 is available with 32 GB of storage and 3 GB of RAM or 64 GB of storage and 4 GB of RAM.^[25] Externally, the case colors were changed to black, emerald, and hibiscus.

The Fire tablets feature multi-touch touchscreen LCD screens. The first generation 7" model contains a Texas Instruments OMAP 4460 processor, while the 8.9" model uses an OMAP 4470 processor.^[26] All three models feature Dolby audio and stereo speakers. The 7" model's speakers are dual-driver, while the 8.9" model's are single-driver.^[26] The device has two Wi-Fi antennas on the 2.4 GHz and 5 GHz bands which utilize MIMO to improve reception.^[26] The Fire HD also added Bluetooth connectivity allowing users to connect an array of wireless accessories including keyboards.^[26] The first generation models have an HDMI port, but this is missing from future generations.

In June 2016, Amazon released a version of the fifth-generation Fire HD 10 that has an aluminum exterior instead of plastic like the other Fire tablets, and is available at the same price as the plastic version.^[27]

The first Fire HD model to get an octa-core processor was the HD 10 tablet released in 2019. USB-C replaced the microUSB for charging in the HD 10 in 2019 and the HD 8 in 2020. The position of the front-facing camera was redesigned to permit landscape video chats in the HD 8 in 2020 and the HD 10 in 2021. Also higher RAM versions were released: 3 GB RAM in the "HD 8 plus" in 2020 and 4 GB RAM in the "HD 10 plus" in 2021.

In 2023, the introduction of the Fire Max 11 added many new features and technologies to the Fire tablet line. Most notably it included active stylus support. All previous models were limited to simple capacitive styluses that behave like a finger, without any enhanced accuracy or features that active styluses are capable of. The Max 11 also included a fingerprint sensor on the power button, as well as a special connector for an external keyboard. It was the first Fire model to ship without a 3.5 mm headphone socket, instead using USB audio over the USB-C connector.

The 2012 models use software that introduced user profiles for sharing among family members and the ability to place absolute limits on total usage or usage of individual features, called FreeTime, and tracks the user's reading speed to predict when the user will finish a chapter or book. The OS is based on a version of Android 4.0.3 "Ice Cream Sandwich". This does not allow use of Google Play, limiting the number of apps accessible for the Fire HD. Fire HD software updates can be received OTA or from the support websites.^[2][28][29]

The Fire HD 7" second generation used Fire OS 3. Note that although this version is called the Fire HD 7", it is not the successor to the original Fire HD. This model is the successor to the Fire second generation. The Fire HD models second generation were updated to FireOS 4.1.1, based on Android 4.4.4, in Q3 2014.

The Fire HD 6" and 7" third generation uses Fire OS 4 "Sangria", which features profiles so each user on the tablet can have their own settings and apps.^[30]

The Fire HD 8 and 10 fifth generation uses Fire OS 5 "Bellini" and was released in late 2015. In September 2016, Amazon released virtual assistant Alexa for the sixth generation Fire tablets.^[31]

The 2018 model of the Fire HD 8 has Fire OS 6 preinstalled, which is based on Android 7.1 "Nougat". It also includes Alexa Hands-Free and the new "Show Mode", in which the tablet acts like an Amazon Echo Show.^[32]

The 2019 model of the Fire HD 10 (and the 2020 model of Fire HD 8) has Fire OS 7 preinstalled, which is based on Android 9 "Pie".^[33]

The 2021 model of the Fire HD 10 / Fire HD 10 Plus introduced 64-bit app support (arm64-v8a Android ABI) for the first time in the Fire HD series.^[34]
