In 2002, AMD introduced the '''Geode GX''' series, which was a re-branding of the National Semiconductor GX2. This was quickly followed by the '''Geode LX''', running up to 667&nbsp;MHz. LX brought many improvements, such as higher speed DDR, a re-designed instruction pipe, and a more powerful display controller. The upgrade from the CS5535 I/O Companion to the CS5536 brought higher speed USB.

Geode GX and LX processors are typically found in devices such as [[thin clients]] and industrial control systems. However, they have come under competitive pressure from [[VIA Technologies|VIA]] on the x86 side, and [[ARM architecture|ARM]] processors from various vendors taking much of the low-end business.

Because of the relative performance, albeit higher [[Performance per watt|PPW]], of the GX and LX core design, AMD introduced the '''Geode NX''', which is an embedded version of the [[Athlon]] processor, K7. Geode NX uses the '''Thoroughbred''' core and is quite similar to the Athlon XP-M that use this core. The Geode NX includes 256 KB of level 2 cache, and runs fanless at up to 1&nbsp;GHz in the NX1500@6&nbsp;W version. The NX2001 part runs at 1.8&nbsp;GHz, the NX1750 part runs at 1.4&nbsp;GHz, and the NX1250 runs at 667&nbsp;MHz.

The Geode NX, with its strong FPU, is particularly suited for embedded devices with graphical performance requirements, such as information kiosks and [[casino]] gaming machines, such as video slots.

However, it was reported that the specific design team for Geode processors in [[Longmont, Colorado]], has been closed, and 75 employees are being relocated to the new development facility in [[Fort Collins, Colorado]]. It is expected that the Geode line of processors will be updated less frequently due to the closure of the Geode design center.<ref>[http://www.xbitlabs.com/news/cpu/display/20060718220033.html X-Bit Labs report] {{Webarchive|url=https://web.archive.org/web/20071024043447/http://www.xbitlabs.com/news/cpu/display/20060718220033.html |date=2007-10-24 }}, retrieved July 19, 2007</ref>

In 2009, comments by AMD indicated that there are no plans for any future microarchitecture upgrades to the processor and that there will be no successor; however, the processors will still be available with the planned availability of the Geode LX extending through 2015.<ref>[https://www.amd.com/us/products/embedded/product-guide-and-buy/Pages/proven-leadership-and-solutions.aspx AMD in Embedded: Proven Leadership and Solutions], retrieved May 24, 2010</ref><ref>{{citation|title=AMD sees no Geode chip replacement in sight|date=2009-01-26|url=https://www.computerworld.com/article/2530500/computer-hardware/amd-sees--no-geode-chip-replacement-in-sight.html}}</ref> In 2016 AMD updated the product roadmap announcing extension of last time buy and shipment for the LX series to 2019.<ref>{{citation|title=AMD Geode LX Processor Family:Longevity|url=https://www.amd.com/en-us/products/embedded/processors/lx#6}}</ref> In early 2018 hardware manufacturer [[congatec]] announced an agreement with AMD for a further extension of availability of congatec's Geode based platforms.<ref>{{citation|title=congatec partners with AMD for long-time support of AMD Geode processors|date=2018-01-16|url=https://www.pressebox.com/pressrelease/congatec-ag/congatec-partners-with-AMD-for-long-time-support-of-AMD-Geode-processors/boxid/888930}}</ref>

==== Geode NX 2001 ====
[[File:KL AMD Geode NX 2001.jpg|thumb|upright=.8|Geode NX 2001.]]
In 2007, there was a ''Geode NX 2001'' model on sale, which was a relabelled [[List of AMD Athlon XP microprocessors#Athlon XP .22Thoroughbred A.2FB.22 .28Model 8.2C 130 nm.29|Athlon XP 2200+ Thoroughbred]]. The processors, with part numbers AANXA2001FKC3G or ANXA2001FKC3D, their specifications are 1.8&nbsp;GHz clock speed, and 1.65 volt core operating voltage. The power consumption is 62.8 Watt. There are no official references to this processor except officials explaining that the batch of CPUs were "being shipped to specific customers", though it is clear it is a desktop Athlon XP CPU core instead of the Mobile [[Athlon#Mobile Athlon XP|Athlon XP-M]] derived Thoroughbred cores of the other Geode NX CPUs, and thus doesn't feature embedded application specific thermal envelope, power consumption and power management features. This kind of "badge engineering" of a particular CPU to accommodate a request for a desktop class chip from an OEM which merely wants to maintain brand recognition and association with the GeodeNX CPUs in its products, but the actual end-product application doesn't necessitate the advanced power and thermal optimization of the GeodeNX CPU's, is understandable, as re-labeling a part in a product catalog, is practically free and the processors do share the same CPU socket ([[Socket A]]).<ref>[http://fab51.com/mobile/tbred/geode_nx2001-e.html Fab51.com information] {{Webarchive|url=https://web.archive.org/web/20100124023734/http://fab51.com/mobile/tbred/geode_nx2001-e.html |date=2010-01-24 }}, retrieved January 22, 2008</ref>
